Chan Chan was the largest city of the pre-Columbian era in South America. It is now an archaeological site in La Libertad Region 5 kilometres west of Trujillo, Peru.Chan Chan is located in the mouth of the Moche Valley and was the capital of the historical empire of the Chimor from 900 to 1470, when they were defeated and incorporated into the Inca Empire. Chimor, a conquest state, developed from the Chimú culture which established itself along the Peruvian coast around 900 AD.Chan Chan is in a particularly arid section of the coastal desert of northern Peru. Due to the lack of rain in this area, the major source of nonsalted water for Chan Chan is in the form of rivers carrying surface runoff from the Andes. This runoff allows for control of land and water through irrigation systems.
The city of Chan Chan spanned 20 km² and had a dense urban center of 6 km² which contained extravagant ciudadelas.
