Machu Picchu

Machu Picchu

Machu Picchu  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. Most of the outlying buildings have been reconstructed in order to give tourists a better idea of what the structures originally looked like. By 1976, thirty percent of Machu Picchu had been restored. The restoration work continues to this day.

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 possible that most of its inhabitants died from smallpox introduced by travelers before the Spanish conquistadors 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 Howland 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 the previous culture that 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 also are 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 exist at 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 as an abode for the deities, 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 Quechua 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 the flora and fauna of the Peruvian Yungas and Central Andean wet puna ecoregions.

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.

Geography

Machu Picchu lies in the southern hemisphere, 13.164 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). 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 blocked easily, should invaders approach along them. Regardless of its original purpose, it is strategically located and readily defended.

The site

The ruins of Machu Picchu are divided into two main sections known as the Urban and Agricultural Sectors, divided by a wall. The Agricultural Sector is further subdivided into Upper and Lower sectors, while the Urban Sector is split into East and West sectors, separated by wide plazas.

The central buildings of Machu Picchu use the classical Inca architectural style of polished dry-stone walls of regular shape. The Incas were masters of this technique, called ashlar, in which blocks of stone are cut to fit together tightly without mortar. Many junctions in the central city are so perfect that it is said not even a blade of grass fits between the stones.

standards this was quick, shoddy construction, and was not used in the building of important structures. Peru is a highly seismic land, and mortar-free construction was more earthquake-resistant than using mortar. The stones of the dry-stone walls built by the Incas can move slightly and resettle without the walls collapsing.

Inca walls had numerous design details that helped protect them against collapsing in an earthquake. Doors and windows are trapezoidal and tilt inward from bottom to top; corners usually are rounded; inside corners often incline slightly into the rooms; and "L"-shaped blocks often were used to tie outside corners of the structure together. These walls do not rise straight from bottom to top, but are offset slightly from row to row.

The Incas never used the wheel in any practical manner. Its use in toys demonstrates that the principle was well-known to them, although it was not applied in their engineering. The lack of strong draft animals, as well as steep terrain and dense vegetation issues, may have rendered the wheel impractical. How they moved and placed the enormous blocks of stones remains a mystery, although the general belief is that they used hundreds of men to push the stones up inclined planes. A few of the stones still have knobs on them that could have been used to lever them into position; it is believed that after the stones were placed, the Incas would have sanded the knobs away, but a few were overlooked.

The space is composed of 140 structures or features, including temples, sanctuaries, parks, and residences that include houses with thatched roofs. There are more than one hundred flights of stone steps — often completely carved from a single block of granite — and numerous water fountains. These were interconnected by channels and water-drains perforated in the rock that were designed for the original irrigation system. Evidence suggests that the irrigation system was used to carry water from a holy spring to each of the houses in turn.

According to archaeologists, the urban sector of Machu Picchu was divided into three great districts: the Sacred District, the Popular District to the south, and the District of the Priests and the Nobility.

The Popular District, or Residential District, is the place where the lower-class people lived. It includes storage buildings and simple houses.

The royalty area, a sector for the nobility, is a group of houses located in rows over a slope; the residence of the Amautas (wise persons) was characterized by its reddish walls, and the zone of the Ñustas (princesses) had trapezoid-shaped rooms. The Monumental Mausoleum is a carved statue with a vaulted interior and carved drawings. It was used for rites or sacrifices.

As part of their road system, the Incas built a road to the Machu Picchu region. Today, tens of thousands of tourists walk the Inca Trail to visit Machu Picchu each year. They acclimate at Cusco before starting on the two- to four-day journey on foot from the Urubamba valley, walking up through the Andes mountain range to the isolated city.

The people of Machu Picchu were connected to long-distance trade, as shown by non-local artifacts found at the site. As an example, Bingham found unmodified obsidian nodules at the entrance gateway. In the 1970s, Burger and Asaro determined that these obsidian samples were from the Titicaca or Chivay obsidian source, and that the samples from Machu Picchu showed long-distance transport of this obsidian type in pre-Hispanic Peru.
