Lost Pyramids Of Caral

Caral is a large settlement in the Supe Valley, near Supe, Barranca province, Peru, some 200 km north of Lima. Caral is one of the most ancient cities of the Americas and possibly of the entire world, and is a well-studied site of the Norte Chico civilization.

Caral was inhabited between roughly 3000 BCE and 2000 BCE, enclosing an area of 66 hectares. Caral was described by its excavators as the oldest urban center in the Americas, a claim that was later challenged as other ancient sites were found nearby. Accommodating more than 3,000 inhabitants, it is the best studied and one of the largest Norte Chico sites known.
