Meaning "old mountain" in Quechua, Machu Picchu is the name given to an ancient Inca city of the Andes built around 1450 and located in the Cordillera Oriental of southern Peru, in the Andes mountain range elevated to 2430 meters. The mountain is located in the region of Cuzco, in the province of Urubamba and on the Sacred Valley of the Incas. To 80 kilometers in the northwest of the city of Cuzco, flows the Urubamba river that crosses the mountain range and gives birth further to a canyon with tropical climate. Many mysteries hover around the origin of this old village: religious sanctuary, royal palace or military fortress? But among all these secrets, the citadel is famous for its dry stone walls, its splendid buildings that take advantage of the astronomical alignments and offer a panoramic view of the valley and its river. This mountain is considered a masterpiece of architecture and engineering. Its mysteries, its architecture and its particular landscapes have made it one of the most appreciated tourist destinations on Earth. Finally, Machu Picchu was declared a "Peruvian Historical Sanctuary" in 1981 and is now on UNESCO's World Heritage List. Considered one of the New Seven Wonders of the Modern World, the site receives 1,500,000 visitors per year.
