Acaray

Acaray, also known as the Fortress of Acaray, is an archaeological site located in the Huaura River Valley on the near north coast of Peru (or the Norte Chico region). The impressive fortress is located on a series of three hilltops, each ringed with a number of perimeter defensive walls that have parapets and bastions, which stand as testaments to the military nature of the site. Radio carbon dating has established it was built about 900-200BC and abandoned 1000–1470AD. Surrounding the hilltop fortress are lower-lying areas of occupation and extensive cemeteries, which have been heavily looted
