The Ware Mounds and Village Site, located west of Ware, Illinois, is an archaeological site comprising three mounds and a 160-acre (65 ha) village site. The site was inhabited by the Late Woodland and Mississippian cultures from c. 800 to c. 1300. The village is one of the only Mississippian villages known to have existed in the Mississippi River valley in Southern Illinois. As the village was located near two major sources of chert, which Mississippian cultures used to make agricultural tools, it was likely a trading center for the mineral.
