About RenovationPlan Your Visit

THE LARGEST PRE-COLUMBIAN SITE NORTH OF MEXICO

As the largest Pre-Columbian Site north of Mexico, Cahokia Mounds covered about 4,000 acres and included at least 120 earthen mounds. The State of Illinois now protects 2,200 acres of the central portion of the site and 72 of the 80 remaining mounds.

The site was named a U.S. National Historic Landmark in 1965, and in 1982, the United Nations Educational, Scientific and Cultural Organization (UNESCO) designated Cahokia Mounds a World Heritage Site for its significance in the Pre-contact history of North America.
