Cahokia, Archaeological site in East St. Louis, United States.
The site contains 80 preserved earthen mounds across 2,200 acres, with Monks Mound standing 100 feet tall and covering 14 acres of land.
Between 600 and 1400 CE, this location developed into the largest pre-Columbian settlement north of Mexico, supporting 20,000 inhabitants at its peak.
The inhabitants established extensive trade networks, created sophisticated pottery, and constructed ceremonial spaces for religious and social gatherings.
The Illinois Department of Natural Resources operates a museum featuring archaeological exhibits, educational programs, and guided tours of the mounds.
The site preserves evidence of advanced agricultural techniques, including raised fields and irrigation systems that sustained large-scale corn production.
