About
About Acaray Fortress
Acaray (often misattributed as 'Inca fortress') crowns a tabular hill 6 km inland in the lower Huaura Valley, Lima, at 250 m. Built c.900–1200 CE by the Huaura–Chancay polity and later used by the Inca, its triple dry-stone perimeter walls (800m total, 6m high) enclose a dense urban core of agglutinated patio-houses, plazas and storage complexes with baffled gates and rectangular bastions. Donald Proulx and Arturo Ruiz Estrada excavations show it guarded the Huaura–Supe coastal desert road between Caral-Supe and Chancay heartland, with posthole evidence of perishable roofs. Visible for miles on the valley's south bank.
