The name means “red fort” in Quechua and comes from the pinkish color the stone takes during some moments of the day, in accordance with the light. It is one of the archaeological sites located at the exit of Cusco, towards the Sacred Valley; it was probably a stronghold for the city protection, as well as a kind of storage for quite a few agricultural products. The view over Cusco is amazing from the esplanade behind the site.
