Machu Picchu is a pre-Columbian 15th-century Inca site located 2,430 metres above sea level. Machu Picchu is located in the Cusco Region of Peru, South America. Often referred to as the "Lost City of the Incas", it is perhaps the most familiar icon of the Inca World.
Machu Picchu has become an important tourist attraction. Since the site was never known to the Spanish during their conquest, it is highly significant as a relatively intact cultural site. Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983. In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide Internet poll.
Machu Picchu was built in the classical Inca style, with polished dry-stone walls.
