The ancient ruins of Machu Picchu are located in Peru. This iconic Incan citadel, often referred to as the “Lost City of the Incas,” sits high in the Andes Mountains at an elevation of approximately 2,430 meters (7,970 feet). Constructed in the 15th century during the reign of Emperor Pachacuti, Machu Picchu showcases impressive stonework and sophisticated agricultural terraces, reflecting the ingenuity of the Inca civilization. Discovered by the outside world in 1911, it has since become one of the most significant archaeological sites and a popular tourist destination, recognized for its historical importance and breathtaking scenery.
