Machu Picchu is a 15th-century Inca citadel situated on a mountain ridge 2,430 metres (7,970 ft) above sea level. Often mistakenly referred to as the "Lost City of the Incas" . Its three primary structures are the Inti Watana, the Temple of the Sun, and the Room of the Three Windows. Most of the outlying buildings have been reconstructed in order to give tourists a better idea of how they originally appeared.

By 1976, thirty percent of Machu Picchu had been restored and restoration continues. Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983.
