About Cahokia Mounds State Historic Site

Cahokia Mounds preserves the remains of a Mississippian city that flourished from about 1050 to 1350 AD, eight miles from downtown St. Louis. About 80 earthen mounds survive across 2,200 acres, and you can follow self-guided or guided trails among them. The centerpiece is Monks Mound, a 100-foot earthwork covering 14 acres, with a reconstructed Woodhenge timber circle to the west. The site has been a UNESCO World Heritage Site since 1982.
