Pataraya: The Archaeology of a Wari Outpost in Nasca

The research reported in this article explores Wari imperial strategies in the upper Nasca Valley of south-central Peru and, building on previous research, documents the flexibility and diversity of those strategies. The focus of these investigations is the site of Pataraya, a small Wari provincial outpost, and its environs. Despite its size, the rectangular enclosure at Pataraya is well planned and conforms to the canons of Wari state architecture documented at other Wari provincial sites. The site was founded early in the Middle Horizon (A.D. 650-1000) and then abandoned during the collapse of the Wari system. Extensive excavation at this condensed version of the Wari building tradition—over 60 percent—uncovered a pattern of spatially segregated use and access within the enclosure. Activities were relegated to specific patio groups with little replication of function, and the sectors themselves were connected by an astonishingly complex system of narrow corridors. The site appears to have been involved in the transfer of coastal products, especially cotton, to the sierra along an ancient road that is also associated with another much larger Wari compound and with the reorganization of an older local site near modern-day Uchuymarca, both of which were also documented during the project.
