Machu Picchu

Machu Picchu (Quechua: Machu Pikchu) – "Old Mountain", is a pre-Columbian 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 Cuzco 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 it was abandoned as an official site for the Inca rulers a century later at the time of the Spanish conquest of the Inca Empire. 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 and, since it was not found and plundered by the Spanish after they conquered the Incas, it is important as a cultural site.

Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983.[2] 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 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.
