Caral and / or Caral settlement was a large settlement in Supe Valley (Supe Valley), near Supe in the province of Barranca (Peru), about 200 km north of Lima. Caral is the oldest town in America. It is a well-researched area of ​​Caral civilization or Norte Chico.

Many years after Ruth Shady Solís explored the ancient city of Caral in Peru, the use of radiocarbon dating was determined by the old buildings of about 2,627 years BC. This timing was adopted by the scientific public in December 2007.

It is still a question of what has happened to this civilization? Why have they left the place and left only ruins?
