Tambomachay is located 8 km. from Cusco and 1 km. from Puca-Pucara and is located on the outskirts of a hill near the main road close to Antisuyo. The name comes from two Quechua words: Tampu, meaning collective housing and Mach‘ay, which means a resting place.
It is also known as Tambo de la Caverna and it takes up an area of 437 square meters, located over 3,700 meters in height. As its name indicates, one can see caverns (machay) nearby, places where, according to indigenous tradition, magic was practiced.
The construction was completely made from sculpted stone and was formed by four walls or terraces on the hill, made by irregular many-angled bases very well assembled. It shows four great niches or vaulted niches in trapezoidal form of an average of 2 meters. In front of the building there was a circular watchtower that had defense and communication purposes.
There is also "The Bath of the Ñusta" or "Inca Maiden’s Bath" which is made of two aqueducts that transport clean water all year long, and which flow into a small stone pond. This had to be a religious pond, where the Inca worshipped the water with the others in the Empire.
The bath looks very much like the one in Ollantaytambo, made of perfectly assembled stones with sculpted borders and sewage ducts. Even though now it is an open-air site, the basis seen to indicate that it was originally a sealed place. The water enters the pond through two artistically sculpted canals. The entrance is through four platforms of a twin-sided trapezoidal porch.
"Everything leads us to think that the place where these ruins are located was the site of the Inca’s favorite residences like a resting spa, and at one time one of the main defensive systems of the Cusco Valley. It is also united to the Imperial Tradition of Pachacutec and Tupac Yupanqui".
