For years it was believed that the first city built in the Americas was in the Andes of South America. More recently, however, archaeologists are excavating a site over a thousand years older than anything previously discovered in an unlikely place: the desert plains of the Supe Valley in Peru

Situated near a river, this site known as Caral has been dated to approximately 2627 B.C. This would mean that the city, which has an extensive complex of pyramids and public buildings, predates even the Great Pyramid of Khufu in Egypt.

Caral was occupied roughly from 3000 BC to 2000 BC, when for some reason the city was abandoned.

One singularly unique thing about Caral is the lack of signs of conflict.

The city had no walls, no fortifications, no signs of any military whatsoever. Even more significant, they found no weapons anywhere.

Carbon dating of sites near Caral have revealed dates as old as 2950 BC, indicating that Caral might have been the culmination of hundreds of years of complex building
