Cahokia Mounds

The remains of the most sophisticated prehistoric native civilization north of Mexico are preserved at Cahokia Mounds State Historic Site. Within the 2,200-acre tract, located a few miles west of Collinsville, Illinois, lie the archaeological remnants of the central section of the ancient settlement that is today known as Cahokia.

The Cahokia Mounds Museum Society is a not-for-profit organization founded in 1976 to support the Cahokia Mounds State Historic Site. Our mission is to promote for the public benefit the educational and scientific aspects of the Cahokia Mounds State Historic Site and associated archaeological sphere, and to support activities that are calculated to preserve, develop or interpret Cahokia Mounds.
