Machu Picchu, the lost city of the Inca, is one of the most important archaeological sites in South America and the most visited tourist attraction in Peru. Despite being located close to the Inca capitol of Cusco the site was never discovered by the Spanish during their conquest, consequently it was not destroyed and remained relatively intact. Machu Picchu (meaning 'Old Peak' in the Quechua language) refers to the mountain that overlooks the city, its Inca name is not known.
