Situated on 2’360 meters above sea level on one of the Andean mountain tops above the Urubamba valley in the Peruvian region Cusco around 75 kilometers northwest from the city of Cusco, the well preserved ruins once used to be a city of the Incas. UNESCO inscribed Machu Picchu on its world cultural heritage list in 1983. (KEYSTONE/Alessandro Della Bella) — Image by © ALESSANDRO DELLA BELLA/Keystone/Corbis
