Cahokia Mounds Museum Society
Cahokia Mounds preserves remains of the largest, most sophisticated prehistoric civilization north of Central Mexico. Inhabited from A.D. 800-1500, up to 20,000 Mississippian Indians resided here during its peak. They made significant advances in astronomy, agriculture and finance and left behind a wealth of information about the past.
Today, Cahokia Mounds is one of only 22 United Nations World Heritage Sites in the United States, and is thereby formally recognized as an irreplaceable property, sharing international significance with precious few, such as Stonehenge and the Pyramids.
The Illinois Historic Preservation Agency administers the site and provides funding for salaries and operating expenses. However, the agency provides little or no funding for public programs, research, marketing or land acquisition, which is why support from the Cahokia Mounds Museum Society is so critical to educating the public about this important cultural gem.
