Choquequirao is a 16th-century Incan site in the Cusco Region of southern Peru. Often called the "sister city" of Machu Picchu due to its similar structure and architecture, the site consists of an extensive complex of buildings and agricultural terraces built around the Sunch'u Pata, the truncated hill top, on a steep mountainside overlooking the Apurímac River. The ruins are situated in the Santa Teresa district at an elevation of 3,050 metres in the rugged Vilcabamba mountain range. The site overlooks the Apurimac River canyon that has an elevation of 1,450 metres (4,760 ft).
