Cahokia Mounds State Historic Site is the location of the largest archaeological site north of Mexico.  It’s a place where 1000 years ago a civilization flourished in the rich Mississippi River bottom land.  This city of Native American people, called Mississippians, supported about 20,000 residents, produced specialized crafts and monumental architecture, and had a stratified political, social, and religious organization.  Their settlement spanned about 5 square miles and originally had about 120 mounds strategically placed on the landscape.  Some of the monuments of this culture are; Woodhenge, an ancient sun calendar made of red cedar posts, and the Stockade, a two-mile long wall that surrounded the central portion of the site.  The pinnacle of their architecture is Monks Mound, which is 14 acres at its base, and rises 100 ft., commanding  a dominating presence in the center of the site.  Today about 80 mounds remain, 70 within the 2200 acres of the central portion of the city that is protected as Cahokia Mounds State Historic Site.  An Interpretive Center provides a gallery, orientation show, and gift shop.  Also available are iPod tours.  Check our website,, for our calendar of events which features several Native American art shows, Kids Day, Archaeology Day, and other cultural events.
