Peru is home to one of the most visited ancient ruins today, Machu Picchu. Machu Picchu is a pre-Columbian 15th-century Inca site located 2,430 metres (7,970 ft) above sea level. Machu Picchu is located in the Cusco Region of Peru, South America. It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 kilometres (50 mi) northwest of Cusco 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.
Today it is a UNESCO World Heritage Site that sees around half a million visitors each year. In January 2010 Machu Piccu was in the news worldwide when heavy rains washed away access roads to the site, trapping over 2,000 tourists and 2,000 locals who then had to be evacuated. Machu Piccu reopened to the public on April 1st, 2010. Most visitors to Machu Piccu stay in the nearby town of Cusco where all manner of accommodation can be found.
