Huaricanga
Huaricanga is the earliest city of the Norte Chico civilization, called Caral or Caral-Supe in Peru and Spanish language sources. Established around 3500 BC, Huaricanga was the oldest city in the Americas. This Late Archaic site is located in the arid Fortaleza Valley on Peru’s north central coast. It is 14 mi (23 km) inland from the Pacific Ocean. The site covers a total area of 100 hectares, and is the largest Late Archaic construction in the Norte Chico region.
The three earthwork mounds on the large site are believed to be remains of pyramidal-shaped structures. Two standing stones, known as huancas, also survive. Excavation in 2007 revealed a structure believed to be a temple, of a design similar to, but predating, the Mito architectural tradition seen in the Peruvian highlands.
In addition, later research in the Fortaleza and Pativilca valleys has found evidence of maize cultivation, as well as fourteen other domesticated species of fruits and vegetables. This suggests that agriculture may have been more important to the development of Caral-Supe civilization than previously thought, as it was for other independent civilizations of the world, such as Mesopotamia, Egypt, China, and India.
