The summit of Cerro Baúl is the location of the most monumental Wari site in the Moquegua region. The map shows Sectors A, B, and C (Williams 2001). The architecture at the site includes building forms identified at Huari, Pikillacta, and other Wari centers, such as Wari patio groups and D-shaped structures. Mapping and excavation reveal that the site is organized into several agglutinated complexes. A large compound on the eastern edge of the monumental core of the site has been identified as an elite residence or a provincial palace complex (see Moseley et al. 2005).
