The trail passes over steep terrain and steps were built to assist traversing, with one section alone containing 2000 steps.
Most Inca architecture was made from precisely cut and shaped stone, fitted together without mortar.
Machu Picchu was built by the Inca’s in 1450 and stands at 7,970 ft above sea level. It was abandoned a century later during the Spanish Conquest and left undiscovered (to the outside world) until Hiram Bingham uncovered it in 1911. It contains agricultural and urban areas and is believed to have primarily used as a royal estate.
