Large Early Intermediate Period and Middle Horizon site located in the northern highlands of Peru near the ruins of Viracochapampa. It was the center of a major polity, the site consisting of a complex of circular and rectangular multi-story buildings of cut stone and surrounded by a stone wall. The center appears to have been important as early as Huari times and to have had some Chimu affiliations. It survived well enough to have been revised and remodeled by the Inca.
