The monumental archaeological complex Mateo Salado has five truncated stepped pyramids (designated A, B, C, D & E) built wall. The largest of these, Pyramid A, was a temple around which the other four were built which possibly functioned as palaces or secondary temples.
Mateo Salado was an administrative and ceremonial center of the Ychsma Culture, then reoccupied by the Incas. The Ychsmas created a walled path next to Pyramid A, typical of the coastal network of Qhapaq Ñan. The archaeological complex is named after the French Matheus Salade (in Spanish, Mateo Salado), who fled the religious persecution in Europe and took refuge there until he was arrested by the Spanish Inquisition, accused of heresy and executed at the stake 1573.
