Cahokia Mounds Once One of the Greatest Cities in the World

    It was once one of the largest cities in the Americas, and remains home to the largest prehistoric manmade earthen construct in the United States. Cahokia Mounds is a state historic site managed by the Illinois Department of Natural Resources, a UNESCO World Heritage Site, and soon could be designated as a National Historical Park.

    The archeology of the area has shed light on the lives and accomplishments of the Mississippian people that once inhabited this land, and the Interpretive Center and surviving mounds at Cahokia continue to educate visitors all year round.
