Tambomachay is an archaeological site associated with the Inca Empire, located near Cusco, Peru. An alternate Spanish name is El Baño del Inca.
It consists of a series of aqueducts, canals and waterfalls that run through the terraced rocks. It is situated near springs such as the one called Timpuc Puquiu, a boiling spring on the northern bank of the Timpuc River and the spring near Huaylla Cocha community. These natural springs were channeled through three waterfalls that still flow today.The function of the site is uncertain: it may have served as a military outpost guarding the approaches to Cusco, as a spa resort for the Incan political elite or imperial baths.
