The architectural complex of Ollantaytambo is located in the district of the same name in the province of Urubamba. The town is approximately 80 km northeast of the city of Cusco, along the Chinchero – Urubamba road.
Ollantaytambo, in the time of the Incas was used as tambo. A tambo was a city – lodging that had the capacity to accommodate thousands of people and they were endowed with gigantic deposits of food, very good roads and places of astronomical observation. They were also characterized by the proper distance that separated them from Cusco, for being located in a main route of the Incanato, which facilitated the rest of the walkers to places of great importance, as in this case the Citadel of Machu Picchu.
The Incas provisioned this water fortress through subterranean aqueducts, whose places of capture were state secrets in their time and until today are not discovered.
Ollantaytambo is the clearest example of how the Incas built the imposing archeological complexes that we can admire until now, as you can appreciate the origin, extraction, carving, transport and perfect assembly of the stones.
