Machu Picchu (Quechua: Machu Pikchu) – Old Mountain) is an Inca site located 2,430 meters (7,970 feet) above sea level situated on a mountain ridge above the Urubamba Valley in Peru. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti during his reign from 1438 to 1472. Often referred to as “The Lost City of the Inca’s”, Machu Picchu is perhaps the most familiar icon of the Inca World.
The Incas started building the estate around 1400 AD 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. Machu Picchu was built in the classical Inca style, with polished dry-stone walls. The primary buildings of Machu Picchu are the Intihuatana, the Temple of the Sun, and the Room of the Three Windows.
