Machu Picchu is the most visited tourist attraction in Peru, located 70km northwest of Cusco in the Andes mountains. It was built in the 15th century as an urban settlement of the Inca Empire but was abandoned just over 100 years later as the Spanish conquered the Inca. It contained temples, sanctuaries and residences and was rediscovered by American historian Hiram Bingham in 1911. Now a UNESCO World Heritage site, over 400,000 tourists visit annually, many taking trains from Cusco and buses up to the site from the station.
