Caral is a large settlement in the Supe Valley,near Supe, Barranca province, or Peru,some 200 km north of Lima. Caral is the most ancient city of the Americas, and is a well-studied site of the Caral civilization or Norte Chico civilization. Caral was inhabited between roughly 2600 BC and 2000 BC[1], and enclosing an area of more than 60 hectares[2]. Caral was described by its excavators as the oldest urban middle in the Americas,a claim that was later challenged as other ancient sites were found nearby.
