Many people still consider the Cahokia site to be a sacred place and Native Americans and metaphysical groups believe Cahokia is a source of powerful psychic energy. The Cahokia Mounds State Historic Site was designated a National Historic Landmark in 1964 and as a World Heritage Site in 1982.
Covering more than 2,000 acres, Cahokia is the most sophisticated prehistoric native civilization north of Mexico. Best known for large, man-made earthen structures, the city of Cahokia was inhabited from about A.D. 700 to 1400. Agricultural fields and a number of smaller villages surrounded and supplied the city.
