Machu Picchu is a pre-Columbian Inca site located high in the Andes Mountains in Peru. Often called "The Lost City of the Incas", it was built in the early 15th century but abandoned a hundred years later when the Spanish conquered the Inca Empire. Though known locally, Machu Picchu was brought to international attention in 1911 by historian Hiram Bingham. It has since become a popular tourist attraction, though some evidence suggests it was discovered by others prior to Bingham. Built in classical Inca style, its primary buildings include the Intihuatana, Temple of the Sun, and Room of Three Windows.
