The Kincaid Mounds Historic Site (11MX2-11; 11PO2-10) circa 1050-1400 CE,[4] is the site of a city from the prehistoric Mississippian culture. One of the largest settlements of the Mississippian culture, it was located at the southern tip of present-day U.S. state of Illinois. Kincaid Mounds has been notable for both its significant role in native North American prehistory and for the central role the site has played in the development of modern archaeological techniques. The site had at least 11 substructure platform mounds (ranking 5th for mound-culture pyramids). Artifacts from the settlement link its major habitation and the construction of the mounds to the Mississippian period, but it was also occupied earlier during the Woodland period.
