New Seven Wonders of the World

New Seven Wonders of the World was a project that attempted to update the Seven Wonders of the Ancient World concept with a modern list of wonders. A popularity poll was led by Canadian-Swiss Bernard Weber  and organized by the Swiss-based, government-controlled New7Wonders Foundation,  with winners announced on July 7, 2007 in Lisbon.

The New7Wonders Foundation claimed that more than 100 million votes were cast through the Internet or by telephone. Nothing prevented multiple votes, so the poll was considered "decidedly unscientific". According to John Zogby, founder and current President/CEO of the Utica, New York-based polling organization Zogby International, New7Wonders Foundation drove “the largest poll on record”.

United Nations

In 2007, the New7Wonders Foundation held a union with the United Nations in recognition of efforts to promote the Millennium Development Goals of the UN. "The UN said:
"The New7Wonders campaigns aim of contributing to the process of raising the welfare and mutual respect of citizens around the world, through encouraging interaction, expression of opinion and direct participation by voting and surveys on hot topics and global problems that are understandable to all. "
However, the United Nations Educational, Scientific and Cultural Organization (UNESCO), in a press release on June 20, 2007, reaffirmed that has no connection with the "private." The statement concludes:
"There is no comparison between Mr Weber mediated campaign and the scientific and educational work resulting from the inscription of sites on the World Heritage List. The list of New 7 Wonders of the World will be the result of a private company, reflecting only the view of those with internet access and not everyone. This initiative can not, in any meaningful and sustainable manner, contribute to the preservation of sites elected by the public.

Egypt

Egyptian commentators saw it as competition to the situation of the Great Pyramid of Giza, the only surviving monument of the original ancient wonders. "This is probably a conspiracy against Egypt, its civilization and monuments," wrote editorialist Al-Sayed al-Naggar in a leading state-owned newspaper. Egyptian Culture Minister Farouq Hosni said the project was "absurd" and described its creator, Weber, like a man "concerned primarily with self-promotion." Nagib Amin, an Egyptian expert on World Heritage, said that "apart from the commercial aspect, the vote has no scientific basis."

After complaints from Egypt, the New7Wonders Foundation designated the Pyramids of Giza - the only remaining of the 7 ancient wonders of the world - as an Honorary New7Wonders Candidate, and removed the vote. However, the Great Pyramid of Giza is not on your official site results.

Brazil

In Brazil there was a campaign of not voting Christ (Vote for the Christ), which was supported by private companies, namely telecommunications operators that stopped charging voters to make phone calls and SMS messages to vote. Moreover, what the corporate sponsors including Banco Bradesco and Rede Globo spent millions of real efforts to bring the statue voted into the top seven. Newsweek reports that the campaign was so pervasive that:
"One morning in June, Rio de Janeiro residents awoke to a text message on their mobile phones ringing:" Press 4916 and vote for Christ. It's free! "The same pitch had been popping up throughout the city from late January through an intermittent electronic screen every time city dwellers swiped their transit cards on city buses and echoing television infomercials that appears a reality-show celebrity posing next to the city marks the statue of Christ the Redeemer. "

According to an article published in Newsweek, about 10 million Brazilians voted in the competition in early July. This number is estimated as the New7Wonders Foundation never gave such details about the campaign.

Peru

An intense campaign led by the Peruvian Ministry of Trade and Tourism in Peru had a great impact on the media and people of Peru both voted massively for their national wonder. The announcement of the new Wonders of the World led to great expectations and the election of Machu Picchu was held around the country, especially in the main square of Cusco and Lima, where President Alan Garcia, organized a ceremony.

Chile


The representative of Chile to Easter Island Moai, Alberto Hotusa, said the organizer Bernard Weber gave him a letter saying that the Moai were morally finished eighth and one of the New Seven Wonders. Hotusa said it was the only participant to receive such an apology.

La India

A campaign to publicize the campaign in India has accelerated and peaked in July 2007 with the news channels, radio stations, and many celebrities asking people to vote for the Taj Mahal. Jordan

Queen Rania Al-Abdullah of Jordan joined the campaign to back Petra, Jordan's national treasure. Although Jordan has a population of just under 7 million people, has stated that more than 14 million votes that were made from the country. This number is estimated as the New7Wonders Foundation never gave such details about the campaign.

Mexico

There was a campaign news programs to encourage people to vote for Chichen Itza.

Taj Mahal

The Taj Mahal (play /ˈtɑːdʒ məˈhɑːl/;  Hindi: ताज महल, from Persian/Urdu: تاج محل "crown of buildings", pronounced [ˈt̪aːdʒ mɛˈɦɛl]; also "the Taj") is a mausoleum located in Agra, India. It is one of the most recognizable structures in the world.[citation needed] It was built by Mughal emperor Shah Jahan in memory of his third wife, Mumtaz Mahal. It is widely considered as one of the most beautiful buildings in the world and stands as a symbol of eternal love.

Taj Mahal is the finest example of Mughal architecture, a style that combines elements from Persian, Islamic and Indian architectural styles.

In 1983, the Taj Mahal became a UNESCO World Heritage Site. While the white domed marble mausoleum is the most familiar component of the Taj Mahal, it is actually an integrated complex of structures. The construction began around 1632 and was completed around 1653, employing thousands of artisans and craftsmen. The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision, including Abd ul-Karim Ma'mur Khan, Makramat Khan, and Ustad Ahmad Lahauri. Lahauri is generally considered to be the principal designer.

Origin and inspiration
In 1631, Shah Jahan, emperor during the Mughal empire's period of greatest prosperity, was grief-stricken when his third wife, Mumtaz Mahal, died during the birth of their 14th child, Gauhara Begum.  Construction of the Taj Mahal began in 1632, one year after her death. The court chronicles of Shah Jahan's grief illustrate the love story traditionally held as an inspiration for Taj Mahal.  The principal mausoleum was completed in 1648 and the surrounding buildings and garden were finished five years later. Emperor Shah Jahan himself described the Taj in these words:
       
Shah Jahan, who commissioned the Taj Mahal -"Shah jahan on a globe" from the Smithsonian Institution
       
Artistic depiction of Mumtaz Mahal

    Should guilty seek asylum here,
    Like one pardoned, he becomes free from sin.
    Should a sinner make his way to this mansion,
    All his past sins are to be washed away.
    The sight of this mansion creates sorrowing sighs;
    And the sun and the moon shed tears from their eyes.
    In this world this edifice has been made;
    To display thereby the creator's glory.

The Taj Mahal incorporates and expands on design traditions of Persian architecture and earlier Mughal architecture. Specific inspiration came from successful Timurid and Mughal buildings including; the Gur-e Amir (the tomb of Timur, progenitor of the Mughal dynasty, in Samarkand), Humayun's Tomb, Itmad-Ud-Daulah's Tomb (sometimes called the Baby Taj), and Shah Jahan's own Jama Masjid in Delhi. While earlier Mughal buildings were primarily constructed of red sandstone, Shah Jahan promoted the use of white marble inlaid with semi-precious stones, and buildings under his patronage reached new levels of refinement.

The tomb
The tomb is the central focus of the entire complex of the Taj Mahal. This large, white marble structure stands on a square plinth and consists of a symmetrical building with an iwan (an arch-shaped doorway) topped by a large dome and finial. Like most Mughal tombs, the basic elements are Persian in origin.

The base structure is essentially a large, multi-chambered cube with chamfered corners, forming an unequal octagon that is approximately 55 metres (180 ft) on each of the four long sides. On each of these sides, a huge pishtaq, or vaulted archway, frames the iwan with two similarly shaped, arched balconies stacked on either side. This motif of stacked pishtaqs is replicated on the chamfered corner areas, making the design completely symmetrical on all sides of the building. Four minarets frame the tomb, one at each corner of the plinth facing the chamfered corners. The main chamber houses the false sarcophagi of Mumtaz Mahal and Shah Jahan; the actual graves are at a lower level.
Viewed from the east

The marble dome that surmounts the tomb is the most spectacular feature. Its height of around 35 metres (115 ft) is about the same as the length of the base, and is accentuated as it sits on a cylindrical "drum" which is roughly 7 metres (23 ft) high. Because of its shape, the dome is often called an onion dome or amrud (guava dome). The top is decorated with a lotus design, which also serves to accentuate its height. The shape of the dome is emphasised by four smaller domed chattris (kiosks) placed at its corners, which replicate the onion shape of the main dome. Their columned bases open through the roof of the tomb and provide light to the interior. Tall decorative spires (guldastas) extend from edges of base walls, and provide visual emphasis to the height of the dome. The lotus motif is repeated on both the chattris and guldastas. The dome and chattris are topped by a gilded finial, which mixes traditional Persian and Hindustani decorative elements.

The main finial was originally made of gold but was replaced by a copy made of gilded bronze in the early 19th century. This feature provides a clear example of integration of traditional Persian and Hindu decorative elements. The finial is topped by a moon, a typical Islamic motif whose horns point heavenward. Because of its placement on the main spire, the horns of the moon and the finial point combine to create a trident shape, reminiscent of traditional Hindu symbols of Shiva.

The minarets, which are each more than 40 metres (130 ft) tall, display the designer's penchant for symmetry. They were designed as working minarets — a traditional element of mosques, used by the muezzin to call the Islamic faithful to prayer. Each minaret is effectively divided into three equal parts by two working balconies that ring the tower. At the top of the tower is a final balcony surmounted by a chattri that mirrors the design of those on the tomb. The chattris all share the same decorative elements of a lotus design topped by a gilded finial. The minarets were constructed slightly outside of the plinth so that, in the event of collapse, (a typical occurrence with many tall constructions of the period) the material from the towers would tend to fall away from the tomb.


Exterior decoration


Calligraphy on large pishtaq
The exterior decorations of the Taj Mahal are among the finest in Mughal architecture.[citation needed] As the surface area changes the decorations are refined proportionally. The decorative elements were created by applying paint, stucco, stone inlays, or carvings. In line with the Islamic prohibition against the use of anthropomorphic forms, the decorative elements can be grouped into either calligraphy, abstract forms or vegetative motifs.
Throughout the complex, passages from the Qur'an are used as decorative elements. Recent scholarship suggests that the passages were chosen by Amanat Khan. The texts refer to themes of judgment and include:
Surah 91 – The Sun
Surah 112 – The Purity of Faith
Surah 89 – Daybreak
Surah 93 – Morning Light
Surah 95 – The Fig
Surah 94 – The Solace
Surah 36 – Ya Sin
Surah 81 – The Folding Up
Surah 82 – The Cleaving Asunder
Surah 84 – The Rending Asunder
Surah 98 – The Evidence
Surah 67 – Dominion
Surah 48 – Victory
Surah 77 – Those Sent Forth
Surah 39 – The Crowds
The calligraphy on the Great Gate reads "O Soul, thou art at rest. Return to the Lord at peace with Him, and He at peace with you."
The calligraphy was created by a calligrapher named Abd ul-Haq, in 1609. Shah Jahan conferred the title of "Amanat Khan" upon him as a reward for his "dazzling virtuosity". Near the lines from the Qur'an at the base of the interior dome is the inscription, "Written by the insignificant being, Amanat Khan Shirazi." Much of the calligraphy is composed of florid thuluth script, made of jasper or black marble, inlaid in white marble panels. Higher panels are written in slightly larger script to reduce the skewing effect when viewed from below. The calligraphy found on the marble cenotaphs in the tomb is particularly detailed and delicate.
Abstract forms are used throughout, especially in the plinth, minarets, gateway, mosque, jawab and, to a lesser extent, on the surfaces of the tomb. The domes and vaults of the sandstone buildings are worked with tracery of incised painting to create elaborate geometric forms. Herringbone inlays define the space between many of the adjoining elements. White inlays are used in sandstone buildings, and dark or black inlays on the white marbles. Mortared areas of the marble buildings have been stained or painted in a contrasting colour, creating geometric patterns of considerable complexity. Floors and walkways use contrasting tiles or blocks in tessellation patterns.
On the lower walls of the tomb there are white marble dados that have been sculpted with realistic bas relief depictions of flowers and vines. The marble has been polished to emphasise the exquisite detailing of the carvings and the dado frames and archway spandrels have been decorated with pietra dura inlays of highly stylised, almost geometric vines, flowers and fruits. The inlay stones are of yellow marble, jasper and jade, polished and leveled to the surface of the walls.



The garden
The complex is set around a large 300-metre (980 ft) square charbagh or Mughal garden. The garden uses raised pathways that divide each of the four quarters of the garden into 16 sunken parterres or flowerbeds. A raised marble water tank at the center of the garden, halfway between the tomb and gateway with a reflecting pool on a north-south axis, reflects the image of the mausoleum. The raised marble water tank is called al Hawd al-Kawthar, in reference to the "Tank of Abundance" promised to Muhammad. Elsewhere, the garden is laid out with avenues of trees and fountains. The charbagh garden, a design inspired by Persian gardens, was introduced to India by the first Mughal emperor, Babur. It symbolizes the four flowing rivers of Jannah (Paradise) and reflects the Paradise garden derived from the Persian paridaeza, meaning 'walled garden'. In mystic Islamic texts of Mughal period, Paradise is described as an ideal garden of abundance with four rivers flowing from a central spring or mountain, separating the garden into north, west, south and east.
Most Mughal charbaghs are rectangular with a tomb or pavilion in the center. The Taj Mahal garden is unusual in that the main element, the tomb, is located at the end of the garden. With the discovery of Mahtab Bagh or "Moonlight Garden" on the other side of the Yamuna, the interpretation of the Archaeological Survey of India is that the Yamuna river itself was incorporated into the garden's design and was meant to be seen as one of the rivers of Paradise. The similarity in layout of the garden and its architectural features with the Shalimar Gardens suggest that they may have been designed by the same architect, Ali Mardan. Early accounts of the garden describe its profusion of vegetation, including abundant roses, daffodils, and fruit trees. As the Mughal Empire declined, the tending of the garden also declined, and when the British took over the management of Taj Mahal during the time of the British Empire, they changed the landscaping to resemble that of lawns of London.


 Outlying buildings
The Taj Mahal complex is bounded on three sides by crenellated red sandstone walls, with the river-facing side left open. Outside the walls are several additional mausoleums, including those of Shah Jahan's other wives, and a larger tomb for Mumtaz's favorite servant. These structures, composed primarily of red sandstone, are typical of the smaller Mughal tombs of the era. The garden-facing inner sides of the wall are fronted by columned arcades, a feature typical of Hindu temples which was later incorporated into Mughal mosques. The wall is interspersed with domed chattris, and small buildings that may have been viewing areas or watch towers like the Music House, which is now used as a museum.





The main gateway (darwaza) is a monumental structure built primarily of marble which is reminiscent of Mughal architecture of earlier emperors. Its archways mirror the shape of tomb's archways, and its pishtaq arches incorporate the calligraphy that decorates the tomb. It utilizes bas-relief and pietra dura inlaid decorations with floral motifs. The vaulted ceilings and walls have elaborate geometric designs, like those found in the other sandstone buildings of the complex.


Interior of the Taj Mahal mosque

Taj Mahal mosque or masjid
At the far end of the complex, there are two grand red sandstone buildings that are open to the sides of the tomb. Their backs parallel the western and eastern walls, and the two buildings are precise mirror images of each other. The western building is a mosque and the other is the jawab (answer), whose primary purpose was architectural balance, although it may have been used as a guesthouse. The distinctions between these two buildings include the lack of mihrab (a niche in a mosque's wall facing Mecca) in the jawab and that the floors of jawab have a geometric design, while the mosque floor was laid with outlines of 569 prayer rugs in black marble. The mosque's basic design of a long hall surmounted by three domes is similar to others built by Shah Jahan, particularly to his Masjid-Jahan Numa, or Jama Masjid, Delhi. The Mughal mosques of this period divide the sanctuary hall into three areas, with a main sanctuary and slightly smaller sanctuaries on either side. At the Taj Mahal, each sanctuary opens onto an enormous vaulting dome. These outlying buildings were completed in 1643.

Petra

Petra (Greek "πέτρα" (petra), meaning rock; Arabic: البتراء, Al-Batrāʾ) is a historical  and archaeological city in the Jordanian governorate of Ma'an that is known for its rock cut architecture and water conduits system. Established sometime around the 6th century BC as the capital city of the Nabataeans,  it is a symbol of Jordan as well as its most visited tourism attraction.  It lies on the slope of Mount Hor  in a basin among the mountains which form the eastern flank of Arabah  (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. Petra has been a UNESCO  World Heritage Site since 1985.

The site remained unknown to the Western world until 1812, when it was introduced by Swiss explorer Johann Ludwig Burckhardt. It was described as "a rose-red city half as old as time" in a Newdigate Prize-winning sonnet by John William Burgon. UNESCO has described it as "one of the most precious cultural properties of man's cultural heritage." Petra was chosen by the BBC as one of "the 40 places you have to see before you die".



Geography

Pliny the Elder and other writers identify Petra as the capital of the Nabataeans and the center of their caravan  trade. Enclosed by towering rocks and watered by a perennial stream, Petra not only possessed the advantages of a fortress, but controlled the main commercial routes which passed through it to Gaza in the west, to Bosra and Damascus in the north, to Aqaba and Leuce Come on the Red Sea, and across the desert to the Persian Gulf.

Excavations have demonstrated that it was the ability of the Nabataeans to control the water supply that led to the rise of the desert city, creating an artificial oasis. The area is visited by flash floods and archaeological evidence demonstrates the Nabataeans controlled these floods by the use of dams, cisterns and water conduits. These innovations stored water for prolonged periods of drought, and enabled the city to prosper from its sale.

Map of Petra

Although in ancient times Petra might have been approached from the south on a track leading around Jabal Haroun ("Aaron's Mountain"), across the plain of Petra, or possibly from the high plateau to the north, most modern visitors approach the site from the east. The impressive eastern entrance leads steeply down through a dark, narrow gorge (in places only 3–4 m (9.8–13 ft) wide) called the Siq ("the shaft"), a natural geological feature formed from a deep split in the sandstone rocks and serving as a waterway flowing into Wadi Musa. At the end of the narrow gorge stands Petra's most elaborate ruin, Al Khazneh (popularly known as "the Treasury"), hewn into the sandstone cliff.

A little further from the Treasury, at the foot of the mountain called en-Nejr, is a massive theatre, so placed as to bring the greatest number of tombs within view. At the point where the valley opens out into the plain, the site of the city is revealed with striking effect. The amphitheatre has been cut into the hillside and into several of the tombs during its construction. Rectangular gaps in the seating are still visible. Almost enclosing it on three sides are rose-coloured mountain walls, divided into groups by deep fissures, and lined with knobs cut from the rock in the form of towers.

History
Evidence suggests that settlements had begun in and around Petra in the eighteenth dynasty of Egypt (1550-1292 BC). It is listed in Egyptian campaign accounts and the Amarna letters as Pel, Sela or Seir. Though the city was founded relatively late, a sanctuary existed there since very ancient times. Stations 19 through 26 of the stations list of Exodus are places associated with Petra.  This part of the country was Biblically assigned to the Horites, the predecessors of the Edomites.  The habits of the original natives may have influenced the Nabataean custom of burying the dead and offering worship in half-excavated caves. Although Petra is usually identified with Sela  which means a rock, the Biblical references refer to it as "the cleft in the rock", referring to its entrance. The second book of Kings xiv. 7 seems to be more specific. In the parallel passage, however, Sela is understood to mean simply "the rock" (2 Chronicles xxv. 12, see LXX).

On the authority of Josephus (Antiquities of the Jews iv. 7, 1~ 4, 7) Eusebius and Jerome (Onom. sacr. 286, 71. 145, 9; 228, 55. 287, 94) assert that Rekem was the native name and Rekem appears in the Dead Sea Scrolls as a prominent Edom site most closely describing Petra and associated with Mount Seir. But in the Aramaic versions Rekem is the name of Kadesh, implying that Josephus may have confused the two places. Sometimes the Aramaic versions give the form Rekem-Geya which recalls the name of the village El-ji, southeast of Petra.[citation needed] The Semitic name of the city, if not Sela, remains unknown. The passage in Diodorus Siculus (xix. 94–97) which describes the expeditions which Antigonus sent against the Nabataeans in 312 BC is understood to throw some light upon the history of Petra, but the "petra" referred to as a natural fortress and place of refuge cannot be a proper name and the description implies that the town was not yet in existence.

The only place in Petra where the name "Rekem" occurs was in the rock wall of the Wadi Musa opposite the entrance to the Siq. About twenty years ago the Jordanians built a bridge over the wadi and this inscription was buried beneath tons of concrete.
More satisfactory evidence of the date of the earliest Nabataean settlement may be obtained from an examination of the tombs. Two types have been distinguished: the Nabataean and the Greco-Roman. The Nabataean type starts from the simple pylon-tomb with a door set in a tower crowned by a parapet ornament, in imitation of the front of a dwelling-house. Then, after passing through various stages, the full Nabataean type is reached, retaining all the native features and at the same time exhibiting characteristics which are partly Egyptian and partly Greek. Of this type there exist close parallels in the tomb-towers at el-I~ejr in north Arabia, which bear long Nabataean inscriptions and supply a date for the corresponding monuments at Petra. Then comes a series of tombfronts which terminate in a semicircular arch, a feature derived from north Syria. Finally come the elaborate façades copied from the front of a Roman temple; however, all traces of native style have vanished. The exact dates of the stages in this development cannot be fixed. Few inscriptions of any length have been found at Petra, perhaps because they have perished with the stucco or cement which was used upon many of the buildings. The simple pylon-tombs which belong to the pre-Hellenic age serve as evidence for the earliest period. It is not known how far back in this stage the Nabataean settlement goes, but it does not go back farther than the 6th century BC.
Urn Tomb

A period follows in which the dominant civilization combines Greek, Egyptian and Syrian elements, clearly pointing to the age of the Ptolemies. Towards the close of the 2nd century BC, when the Ptolemaic and Seleucid kingdoms were equally depressed, the Nabataean kingdom came to the front. Under Aretas III Philhellene, (c.85–60 BC), the royal coins begin. The theatre was probably excavated at that time, and Petra must have assumed the aspect of a Hellenistic city. In the reign of Aretas IV Philopatris, (9 BC–40 AD), the fine tombs of the el-I~ejr  type may be dated, and perhaps also the great High-place.


Roman rule
In 106 AD, when Cornelius Palma was governor of Syria, that part of Arabia under the rule of Petra was absorbed into the Roman Empire as part of Arabia Petraea, becoming capital. The native dynasty came to an end. But the city continued to flourish. A century later, in the time of Alexander Severus, when the city was at the height of its splendor, the issue of coinage comes to an end. There is no more building of sumptuous tombs, owing apparently to some sudden catastrophe, such as an invasion by the neo-Persian power under the Sassanid Empire. Meanwhile, as Palmyra (fl. 130–270) grew in importance and attracted the Arabian trade away from Petra, the latter declined. It seems, however, to have lingered on as a religious centre. A Roman road was constructed at the site. Epiphanius of Salamis (c.315–403) writes that in his time a feast was held there on December 25 in honor of the virgin Khaabou (Chaabou) and her offspring Dushara  (Haer. 51)

Religion
The Nabataeans worshipped the Arab  gods and goddesses  of the pre-Islamic times as well as a few of their deified kings. One, Obodas I, was deified after his death. Dushara was the main male god accompanied by his female trinity: Al-‘Uzzá, Allat and Manāt. Many statues carved in the rock depict these gods and goddesses.

The Monastery, Petra's largest monument, dates from the 1st century BC. It was dedicated to Obodas I and is believed to be the symposium of Obodas the god. This information is inscribed on the ruins of the Monastery (the name is the translation of the Arabic "Ad Deir").

Christianity found its way to Petra in the 4th century AD, nearly 500 years after the establishment of Petra as a trade center. Athanasius mentions a bishop of Petra (Anhioch. 10) named Asterius. At least one of the tombs (the "tomb with the urn"?) was used as a church. An inscription in red paint records its consecration "in the time of the most holy bishop Jason" (447). After the Islamic conquest of 629–632 Christianity in Petra, as of most of Arabia, gave way to Islam. During the First Crusade Petra was occupied by Baldwin I of the Kingdom of Jerusalem and formed the second fief of the barony of Al Karak (in the lordship of Oultrejordain) with the title Château de la Valée de Moyse or Sela. It remained in the hands of the Franks until 1189. It is still a titular see of the Catholic Church.

According to Arab tradition, Petra is the spot where Moses (Musa) struck a rock with his staff and water came forth, and where Moses' brother, Aaron (Harun), is buried, at Mount Hor, known today as Jabal Haroun or Mount Aaron. The Wadi Musa or "Wadi of Moses" is the Arab name for the narrow valley at the head of which Petra is sited. A mountaintop shrine of Moses' sister Miriam was still shown to pilgrims at the time of Jerome in the 4th century, but its location has not been identified since.

Decline
Petra declined rapidly under Roman rule, in large part from the revision of sea-based trade routes. In 363 an earthquake destroyed many buildings, and crippled the vital water management system.  The ruins of Petra were an object of curiosity in the Middle Ages and were visited by Sultan Baibars of Egypt towards the end of the 13th century. The first European to describe them was Johann Ludwig Burckhardt in 1812.

Because the structures weakened with age, many of the tombs became vulnerable to thieves, and many treasures were stolen.

Machu Picchu

Machu Picchu (Quechua: Machu Pikchu [ˈmɑtʃu ˈpixtʃu], "Old Peaks") is a pre-Columbian 15th-century Inca  site located 2,430 metres (7,970 ft) above sea level. It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 kilometres (50 mi) northwest of Cusco and through which the Urubamba River  flows. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438–1472). Often referred to as "The Lost City of the Incas", it is perhaps the most familiar icon of the Inca World.

The Incas started building the "estate" around AD 1400 but abandoned it as an official site for the Inca rulers a century later at the time of the Spanish Conquest. Although known locally, it was unknown to the outside world before being brought to international attention in 1911 by the American historian Hiram Bingham. Since then, Machu Picchu has become an important tourist attraction.

Since the site was never known to the Spanish during their conquest, it is highly significant as a relatively intact cultural site. Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983. In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide Internet poll.

Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its three primary buildings are the Intihuatana, the Temple of the Sun, and the Room of the Three Windows. These are located in what is known by archaeologists as the Sacred District of Machu Picchu. In September 2007, Peru and Yale University almost reached an agreement regarding the return of artifacts which Yale has held since Hiram Bingham removed them from Machu Picchu in the early 20th century. In November 2010, a Yale University representative agreed to return the artifacts to a Peruvian university.



History

Machu Picchu was built around 1450, at the height of the Inca Empire.  It was abandoned just over 100 years later, in 1572, as a belated result of the Spanish Conquest.  It is likely that most of its inhabitants died from smallpox introduced by travelers before the Spanish conquistadores arrived in the area.  The latter had notes of a place called Piccho, although there is no record of the Spanish having visited the remote city. The types of sacred rocks defaced by the conquistadors in other locations are untouched at Machu Picchu.

Hiram Bingham theorized that the complex was the traditional birthplace of the Incan "Virgins of the Suns". More recent research by scholars such as John Rowe and Richard Burger, has convinced most archaeologists that Machu Picchu was an estate of the Inca emperor Pachacuti. In addition, Johan Reinhard presented evidence that the site was selected because of its position relative to sacred landscape features such as its mountains, which are purported to be in alignment with key astronomical events important to the Incas.

Johan Reinhard believes Machu Picchu to be a sacred religious site. This theory stands mainly because of where Machu Picchu is located. Reinhard calls it "sacred geography" because the site is built on and around mountains that hold high religious importance in the Inca culture and in culture that previously occupied the land. At the highest point of the mountain in which Machu Picchu was named after, there are “artificial platforms [and] these had a religious function, as is clear from the Inca ritual offerings found buried under them” (Reinhard 2007). These platforms are also found in other Incan religious sites. The site’s other stone structures have finely worked stones with niches and from what the “Spaniards wrote about Inca sites, we know that these [types of] building[s] were of ritual significance” (Reinhard 2007). This would be the most convincing evidence that Reinhard points out because this type of stylistic stonework is only found at the religious sites so it would be natural that they would put it into this religious site.  Another theory maintains that Machu Picchu was an Inca llaqta, a settlement built to control the economy of conquered regions. Yet another asserts that it may have been built as a prison for a select few who had committed heinous crimes against Inca society. An alternative theory is that it is an agricultural testing station. Different types of crops could be tested in the many different micro-climates afforded by the location and the terraces; these were not large enough to grow food on a large scale, but may have been used to determine what could grow where. Another theory suggests that the city was built for the gods to live in, or for the coronation of kings.

Although the citadel is located only about 80 kilometers (50 miles) from Cusco, the Inca capital, the Spanish never found it and consequently did not plunder or destroy it, as they did many other sites. Over the centuries, the surrounding jungle grew over much of the site, and few outsiders knew of its existence.

On 24 July 1911, Hiram Bingham announced the discovery of Machu Picchu to scholars. An American historian employed as a lecturer at Yale University, Bingham had been searching for the city of Vilcabamba, the last Inca refuge during the Spanish conquest. He had worked for years in previous trips and explorations around the zone. Pablito Alvarez, a local 11 year-old Quechuas boy, led Bingham up to Machu Picchu. Some Quechuas lived in the original structures at Machu Picchu.

Bingham started archaeological studies and completed a survey of the area. He called the complex "The Lost City of the Incas", which was the title of his first book. Bingham made several more trips and conducted excavations on the site through 1915, collecting various artifacts which he took back to Yale. He wrote a number of books and articles about the discovery of Machu Picchu.

The site received significant publicity after the National Geographic Society devoted their entire April 1913 issue to Machu Picchu.

In 1981 Peru declared an area of 325.92 square kilometers surrounding Machu Picchu as a "Historical Sanctuary". In addition to the ruins, the sanctuary includes a large portion of the adjoining region, rich with flora and fauna.

In 1983 UNESCO designated Machu Picchu a World Heritage Site, describing it as "an absolute masterpiece of architecture and a unique testimony to the Inca civilization".

The World Monuments Fund placed Machu Picchu on its 2008 Watch List of the 100 Most Endangered Sites in the world because of environmental degradation. This has resulted from the impact of tourism, uncontrolled development in the nearby town of Aguas Calientes, which included a poorly sited tram to ease visitor access, and the construction of a bridge across the Vilcanota River, which is likely to bring even more tourists to the site, in defiance of a court order and government protests against it.


Early encounters
Although Bingham was the first person to bring word of the ruins to the outside world, other outsiders were said to have seen Machu Picchu before him. Simone Waisbard, a long-time researcher of Cusco, claims that Enrique Palma, Gabino Sánchez, and Agustín Lizárraga left their names engraved on one of the rocks at Machu Picchu on 14 July 1901. In 1904, an engineer named Franklin supposedly spotted the ruins from a distant mountain. He told Thomas Payne, an English Christian missionary living in the region, about the site, Payne's family members claim. They also report that in 1906, Payne and fellow missionary Stuart E. McNairn (1867–1956) climbed up to the ruins.

The site may have been discovered and plundered in 1867 by a German businessman, Augusto Berns. There is some evidence that a German engineer, J. M. von Hassel, arrived earlier. Maps found by historians show references to Machu Picchu as early as 1874.

Geography
Machu Picchu lies in the southern hemisphere, some 13 degrees south of the equator.  It is 80 kilometers northwest of Cusco, on the crest of the mountain Machu Picchu, located about 2,450 metres (8,040 ft) above mean sea level, over 1,000 metres (3,300 ft) lower than Cusco, which has an altitude of 3,600 metres (11,800 ft).[13]  As such, it had a milder climate than the Inca capital. It is one of the most important archaeological sites in South America, one of the most visited tourist attractions in all of Latin America and the most visited tourist attraction in Peru.

The year at Machu Picchu is divided between wet and dry seasons, with the majority of annual rain falling from October through to April. It can rain at any time of the year.

Machu Picchu is situated above a loop of the Urubamba River, which surrounds the site on three sides, with cliffs dropping vertically for 450 metres (1,480 ft) to the river at their base. The area is subject to morning mists rising from the river. The location of the city was a military secret, and its deep precipices and steep mountains provided excellent natural defenses. The Inca Bridge, an Inca rope bridge, across the Urubamba River in the Pongo de Mainique, provided a secret entrance for the Inca army. Another Inca bridge was built to the west of Machu Picchu, the tree-trunk bridge, at a location where a gap occurs in the cliff that measures 6 metres (20 ft). It could be bridged by two tree trunks, but with the trees removed, there was a 570 metres (1,870 ft) fall to the base of the cliffs.

The city sits in a saddle between the two mountains Machu Picchu and Huayna Picchu, with a commanding view down two valleys and a nearly impassable mountain at its back. It has a water supply from springs that cannot be blocked easily, and enough land to grow food for about four times as many people as ever lived there. The hillsides leading to it have been terraced, not only to provide more farmland to grow crops, but to steepen the slopes which invaders would have to ascend. The terraces reduced soil erosion and protected against landslides. Two high-altitude routes from Machu Picchu go across the mountains back to Cusco, one through the sun gate, and the other across the Inca bridge. Both could be easily blocked, should invaders approach along them. Regardless of its original purpose, it is strategically located and readily defended.

Great Wall of China

The Great Wall of China is a series of stone and earthen fortifications  in northern China, built originally to protect the northern borders of the Chinese Empire against intrusions by various nomadic groups. Several walls have been built since the 5th century BC that are referred to collectively as the Great Wall, which has been rebuilt and maintained from the 5th century BC through the 16th century. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; the majority of the existing wall was built during the Ming Dynasty.

The Great Wall stretches from Shanhaiguan in the east, to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. The most comprehensive archaeological survey, using advanced technologies, has concluded that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi). This is made up of 6,259.6 km (3,889.5 mi) sections of actual wall, 359.7 km (223.5 mi) of trenches and 2,232.5 km (1,387.2 mi) of natural defensive barriers such as hills and rivers.



History
The Chinese were already familiar with the techniques of wall-building by the time of the Spring and Autumn Period, which began around the 8th century BC.  During the Warring States Period from the 5th century BC to 221 BC, the states of Qin, Wei, Zhao, Qi, Yan  and Zhongshan all constructed extensive fortifications to defend their own borders. Built to withstand the attack of small arms such as swords and spears, these walls were made mostly by stamping earth and gravel between board frames.

Qin Shi Huang conquered all opposing states and unified China in 221 BC, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall to connect the remaining fortifications along the empire's new northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains. There are no surviving historical records indicating the exact length and course of the Qin Dynasty walls. Most of the ancient walls have eroded away over the centuries, and very few sections remain today. Later, the Han, Sui, Northern and Jin dynasties all repaired, rebuilt, or expanded sections of the Great Wall at great cost to defend themselves against northern invaders. It is estimated that over 1 million workers died building the wall.
The Great Wall concept was revived again during the Ming Dynasty, following the Ming army's defeat by the Oirats in the Battle of Tumu in 1449. The Ming had failed to gain a clear upper-hand over the Manchurian and Mongolian tribes after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the nomadic tribes out by constructing walls along the northern border of China. Acknowledging the Mongol control established in the Ordos Desert, the wall followed the desert's southern edge instead of incorporating the bend of the Huang He.

Unlike the earlier Qin fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth. As Mongol raids continued periodically over the years, the Ming devoted considerable resources to repair and reinforce the walls. Sections near the Ming capital of Beijing were especially strong.[citation needed]

During the 1440s–1460s, the Ming also built a so-called "Liaodong Wall". Similar in function to the Great Wall (whose extension, in a sense, it was), but more basic in construction, the Liaodong Wall enclosed the agricultural heartland of the Liaodong province, protecting it against potential incursions by Jurched-Mongol Oriyanghan from the northwest and the Jianzhou Jurchens from the north. While stones and tiles were used in some parts of the Liaodong Wall, most of it was in fact simply an earth dike with moats on both sides.

Towards the end of the Ming Dynasty, the Great Wall helped defend the empire against the Manchu invasions that began around 1600. Under the military command of Yuan Chonghuan, the Ming army held off the Manchus at the heavily fortified Shanhaiguan pass, preventing the Manchus from entering the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, when the gates at Shanhaiguan were opened by Wu Sangui, a Ming border general who disliked the activities of rulers of the Shun Dynasty. The Manchus quickly seized Beijing, and defeated the newly founded Shun Dynasty and remaining Ming resistance, to establish the Qing Dynasty.

In 2009, an additional 290 km (180 mi) of previously undetected portions of the wall, built during the Ming Dynasty, were discovered. The newly discovered sections range from the Hushan mountains in the northern Liaoning province, to Jiayuguan in western Gansu province. The sections had been submerged over time by sandstorms which moved across the arid region.


Notable areas
Some of the following sections are in Beijing municipality, which were renovated and which are regularly visited by modern tourists today.

    * "North Pass" of Juyongguan pass, known as the Badaling. When used by the Chinese to protect their land, this section of the wall has had many guards to defend China’s capital Beijing. Made of stone and bricks from the hills, this portion of the Great Wall is 7.8 meters (25.6 ft) high and 5 meters (16.4 ft) wide.
    * "West Pass" of Jiayuguan (pass). This fort is near the western edges of the Great Wall.
    * "Pass" of Shanhaiguan. This fort is near the eastern edges of the Great Wall.
    * One of the most striking sections of the Ming Great Wall is where it climbs extremely steep slopes. It runs 11 kilometers (7 mi) long, ranges from 5 to 8 meters (16–26 ft) in height, and 6 meters (19.7 ft) across the bottom, narrowing up to 5 meters (16.4 ft) across the top. Wangjinglou is one of Jinshanling's 67 watchtowers, 980 meters (3,215 ft) above sea level.
    * South East of Jinshanling, is the Mutianyu Great Wall which winds along lofty, cragged mountains from the southeast to the northwest for approximately 2.25 kilometers (about 1.3 miles). It is connected with Juyongguan Pass to the west and Gubeikou to the east.
    * 25 km (16 mi) west of the Liao Tian Ling stands apart of Great Wall which is only 2~3 stories high. According to the records of Lin Tian, the wall was not only extremely short compared to others, but it appears to be silver. Archeologists explain that the wall appears to be silver because the stone they used were from Shan Xi, where many mines are found. The stone contains extremely high levels of metal in it causing it to appear silver. However, due to years of decay of the Great Wall, it is hard to see the silver part of the wall today.






Colosseum

The Colosseum, or the Coliseum, originally the Flavian Amphitheatre (Latin: Amphitheatrum Flavium, Italian Anfiteatro Flavio or Colosseo), is an elliptical amphitheatre  in the centre of the city of Rome, Italy, the largest ever built in the Roman Empire. It is considered one of the greatest works of Roman architecture and Roman engineering.

Occupying a site just east of the Roman Forum, its construction started in 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96). The name "Amphitheatrum Flavium" derives from both Vespasian's and Titus's family name (Flavius, from the gens Flavia).

Capable of seating 50,000 spectators, the Colosseum was used for gladiatorial contests and public spectacles such as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine.

Although in the 21st century it stays partially ruined because of damage caused by devastating earthquakes and stone-robbers, the Colosseum is an iconic symbol of Imperial Rome. It is one of Rome's most popular tourist attractions and still has close connections with the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" procession that starts in the area around the Colosseum.



Name
The Colosseum's original Latin name was Amphitheatrum Flavium, often anglicized as Flavian Amphitheater. The building was constructed by emperors of the Flavian dynasty, hence its original name, after the reign of Emperor Nero.  This name is still used in modern English, but generally the structure is better known as the Colosseum. In antiquity, Romans may have referred to the Colosseum by the unofficial name Amphitheatrum Caesareum; this name could have been strictly poetic.  This name was not exclusive to the Colosseum; Vespasian and Titus, builders of the Colosseum, also constructed an amphitheater of the same name  in Puteoli (modern Pozzuoli).

The name Colosseum has long been believed to be derived from a colossal statue of Nero nearby (the statue of Nero itself being named after one of the original ancient wonders, the Colossus of Rhodes)[citation needed]. This statue was later remodeled by Nero's successors into the likeness of Helios (Sol) or Apollo, the sun god, by adding the appropriate solar crown. Nero's head was also replaced several times with the heads of succeeding emperors. Despite its pagan links, the statue remained standing well into the medieval era and was credited with magical powers. It came to be seen as an iconic symbol of the permanence of Rome.

In the 8th century, a famous epigram attributed to the Venerable Bede celebrated the symbolic significance of the statue in a prophecy that is variously quoted: Quamdiu stat Colisæus, stat et Roma; quando cadet colisæus, cadet et Roma; quando cadet Roma, cadet et mundus ("as long as the Colossus stands, so shall Rome; when the Colossus falls, Rome shall fall; when Rome falls, so falls the world"). This is often mistranslated to refer to the Colosseum rather than the Colossus (as in, for instance, Byron's poem Childe Harold's Pilgrimage). However, at the time that the Pseudo-Bede wrote, the masculine noun coliseus was applied to the statue rather than to what was still known as the Flavian amphitheatre.

The Colossus did eventually fall, possibly being pulled down to reuse its bronze. By the year 1000 the name "Colosseum" had been coined to refer to the amphitheatre. The statue itself was largely forgotten and only its base survives, situated between the Colosseum and the nearby Temple of Venus and Roma


History
AncientConstruction of the Colosseum began under the rule of the Emperor Vespasian  in around 70–72AD. The site chosen was a flat area on the floor of a low valley between the Caelian, Esquiline and Palatine Hills, through which a canalised stream ran. By the 2nd century BC the area was densely inhabited. It was devastated by the Great Fire of Rome in AD 64, following which Nero seized much of the area to add to his personal domain. He built the grandiose Domus Aurea on the site, in front of which he created an artificial lake surrounded by pavilions, gardens and porticoes. The existing Aqua Claudia aqueduct was extended to supply water to the area and the gigantic bronze Colossus of Nero  was set up nearby at the entrance to the Domus Aurea.

Although the Colossus was preserved, much of the Domus Aurea was torn down. The lake was filled in and the land reused as the location for the new Flavian Amphitheatre. Gladiatorial schools and other support buildings were constructed nearby within the former grounds of the Domus Aurea. According to a reconstructed inscription found on the site, "the emperor Vespasian ordered this new amphitheatre to be erected from his general's share of the booty." This is thought to refer to the vast quantity of treasure seized by the Romans following their victory in the Great Jewish Revolt in 70AD. The Colosseum can be thus interpreted as a great triumphal monument built in the Roman tradition of celebrating great victories, placating the Roman people instead of returning soldiers. Vespasian's decision to build the Colosseum on the site of Nero's lake can also be seen as a populist gesture of returning to the people an area of the city which Nero had appropriated for his own use. In contrast to many other amphitheatres, which were located on the outskirts of a city, the Colosseum was constructed in the city centre; in effect, placing it both literally and symbolically at the heart of Rome.

The Colosseum had been completed up to the third story by the time of Vespasian's death in 79. The top level was finished and the building inaugurated by his son, Titus, in 80. Dio Cassius recounts that over 9,000 wild animals were killed during the inaugural games of the amphitheatre. The building was remodelled further under Vespasian's younger son, the newly designated Emperor Domitian, who constructed the hypogeum, a series of underground tunnels used to house animals and slaves. He also added a gallery to the top of the Colosseum to increase its seating capacity.

In 217, the Colosseum was badly damaged by a major fire (caused by lightning, according to Dio Cassius) which destroyed the wooden upper levels of the amphitheatre's interior. It was not fully repaired until about 240 and underwent further repairs in 250 or 252 and again in 320. An inscription records the restoration of various parts of the Colosseum under Theodosius II and Valentinian III (reigned 425–455), possibly to repair damage caused by a major earthquake in 443; more work followed in 484 and 508. The arena continued to be used for contests well into the 6th century, with gladiatorial fights last mentioned around 435. Animal hunts continued until at least 523, when Anicius Maximus celebrated his consulship with some venationes, criticised by King Theodoric the Great for their high cost.


Medieval
The Colosseum underwent several radical changes of use during the medieval period. By the late 6th century a small church had been built into the structure of the amphitheatre, though this apparently did not confer any particular religious significance on the building as a whole. The arena was converted into a cemetery. The numerous vaulted spaces in the arcades under the seating were converted into housing and workshops, and are recorded as still being rented out as late as the 12th century. Around 1200 the Frangipani family  took over the Colosseum and fortified it, apparently using it as a castle.

Severe damage was inflicted on the Colosseum by the great earthquake in 1349, causing the outer south side, lying on a less stable alluvional terrain, to collapse. Much of the tumbled stone was reused to build palaces, churches, hospitals and other buildings elsewhere in Rome. A religious order moved into the northern third of the Colosseum in the mid-14th century and continued to inhabit it until as late as the early 19th century. The interior of the amphitheatre was extensively stripped of stone, which was reused elsewhere, or (in the case of the marble façade) was burned to make quicklime. The bronze clamps which held the stonework together were pried or hacked out of the walls, leaving numerous pockmarks which still scar the building today.


Modern
During the 16th and 17th century, Church officials sought a productive role for the vast derelict hulk of the Colosseum. Pope Sixtus V (1585–1590) planned to turn the building into a wool factory to provide employment for Rome's prostitutes, though this proposal fell through with his premature death.  In 1671 Cardinal Altieri authorized its use for bullfights; a public outcry caused the idea to be hastily abandoned.

In 1749, Pope Benedict XIV endorsed as official Church policy the view that the Colosseum was a sacred site where early Christians had been martyred. He forbade the use of the Colosseum as a quarry and consecrated the building to the Passion of Christ and installed Stations of the Cross, declaring it sanctified by the blood of the Christian martyrs who perished there (see Christians and the Colosseum). However there is no historical evidence to support Benedict's claim, nor is there even any evidence that anyone prior to the 16th century suggested this might be the case; the Catholic Encyclopedia concludes that there are no historical grounds for the supposition. Later popes initiated various stabilization and restoration projects, removing the extensive vegetation which had overgrown the structure and threatened to damage it further. The façade was reinforced with triangular brick wedges in 1807 and 1827, and the interior was repaired in 1831, 1846 and in the 1930s. The arena substructure was partly excavated in 1810–1814 and 1874 and was fully exposed under Benito Mussolini in the 1930s.

The Colosseum is today one of Rome's most popular tourist attractions, receiving millions of visitors annually. The effects of pollution and general deterioration over time prompted a major restoration programme carried out between 1993 and 2000, at a cost of 40 billion Italian lire ($19.3m / €20.6m at 2000 prices). In recent years it has become a symbol of the international campaign against capital punishment, which was abolished in Italy in 1948. Several anti–death penalty demonstrations took place in front of the Colosseum in 2000. Since that time, as a gesture against the death penalty, the local authorities of Rome change the color of the Colosseum's night time illumination from white to gold whenever a person condemned to the death penalty anywhere in the world gets their sentence commuted or is released, or if a jurisdiction abolishes the death penalty. Most recently, the Colosseum was illuminated in gold when capital punishment was abolished in the American state of New Mexico in April 2009.
Today, the Colosseum is a background to the busy metropolis that is modern Rome.

Because of the ruined state of the interior, it is impractical to use the Colosseum to host large events; only a few hundred spectators can be accommodated in temporary seating. However, much larger concerts have been held just outside, using the Colosseum as a backdrop. Performers who have played at the Colosseum in recent years have included Ray Charles (May 2002), Paul McCartney (May 2003), Elton John (September 2005), and Billy Joel (July 2006).


Arena and hypogeum
The arena itself was 83 meters by 48 meters (272 ft by 157 ft / 280 by 163 Roman feet).  It comprised a wooden floor covered by sand (the Latin word for sand is harena or arena), covering an elaborate underground structure called the hypogeum (literally meaning "underground"). Little now remains of the original arena floor, but the hypogeum is still clearly visible. It consisted of a two-level subterranean network of tunnels and cages beneath the arena where gladiators and animals were held before contests began. Eighty vertical shafts provided instant access to the arena for caged animals and scenery pieces concealed underneath; larger hinged platforms, called hegmata, provided access for elephants and the like. It was restructured on numerous occasions; at least twelve different phases of construction can be seen.

The hypogeum was connected by underground tunnels to a number of points outside the Colosseum. Animals and performers were brought through the tunnel from nearby stables, with the gladiators' barracks at the Ludus Magnus to the east also being connected by tunnels. Separate tunnels were provided for the Emperor and the Vestal Virgins to permit them to enter and exit the Colosseum without needing to pass through the crowds.

Substantial quantities of machinery also existed in the hypogeum. Elevators and pulleys raised and lowered scenery and props, as well as lifting caged animals to the surface for release. There is evidence for the existence of major hydraulic mechanisms and according to ancient accounts, it was possible to flood the arena rapidly, presumably via a connection to a nearby aqueduct.


Use
The Colosseum was used to host gladiatorial  shows as well as a variety of other events. The shows, called munera, were always given by private individuals rather than the state. They had a strong religious element but were also demonstrations of power and family prestige, and were immensely popular with the population. Another popular type of show was the animal hunt, or venatio. This utilized a great variety of wild beasts, mainly imported from Africa and the Middle East, and included creatures such as rhinoceros, hippopotamuses, elephants, giraffes, aurochs, wisents, barbary lions, panthers, leopards, bears, caspian tigers, crocodiles  and ostriches. Battles and hunts were often staged amid elaborate sets with movable trees and buildings. Such events were occasionally on a huge scale; Trajan is said to have celebrated his victories in Dacia  in 107 with contests involving 11,000 animals and 10,000 gladiators over the course of 123 days.

During the early days of the Colosseum, ancient writers recorded that the building was used for naumachiae (more properly known as navalia proelia) or simulated sea battles. Accounts of the inaugural games held by Titus in AD 80 describe it being filled with water for a display of specially trained swimming horses and bulls. There is also an account of a re-enactment of a famous sea battle between the Corcyrean (Corfiot) Greeks and the Corinthians. This has been the subject of some debate among historians; although providing the water would not have been a problem, it is unclear how the arena could have been waterproofed, nor would there have been enough space in the arena for the warships to move around. It has been suggested that the reports either have the location wrong, or that the Colosseum originally featured a wide floodable channel down its central axis (which would later have been replaced by the hypogeum).

Sylvae or recreations of natural scenes were also held in the arena. Painters, technicians and architects would construct a simulation of a forest with real trees and bushes planted in the arena's floor. Animals would be introduced to populate the scene for the delight of the crowd. Such scenes might be used simply to display a natural environment for the urban population, or could otherwise be used as the backdrop for hunts or dramas depicting episodes from mythology. They were also occasionally used for executions in which the hero of the story — played by a condemned person — was killed in one of various gruesome but mythologically authentic ways, such as being mauled by beasts or burned to death.
