Sites and architecture
Caral–Supe sites are known for their density of large sites with immense architecture. Haas argues that the density of sites in such a small area is globally unique for a nascent civilization. During the third millennium BCE, Caral–Supe may have been the most densely populated area of the world (excepting, possibly, Northern China). The Supe, Pativilca, Fortaleza, and Huaura River Valleys of Caral–Supe each have several related sites.
