Machu Picchu, Lost City of the Incas
Machu Picchu is a pre-Columbian Inca
site located 2,430 metres (8,000 ft) above sea level. It is situated on
a mountain ridge above the Urubamba Valley in Peru, which is 80 km (50
mi) northwest of Cusco and through which the Urubamba River flows. The
river is a partially navigable headwater of the Amazon River. Often
referred to as "The Lost City of the Incas", Machu Picchu is one of the
most familiar symbols of the Inca Empire.
