Overview
Cahokia was the largest pre-Columbian settlement north of Mexico, with a peak population estimated at 10,000–20,000 people around 1100 CE. The site contains Monks Mound, the largest prehistoric earthwork in the Americas, covering more than 13 acres at its base.
Historical significance
Cahokia was designated a UNESCO World Heritage Site in 1982 and is among the most studied archaeological sites in North America. It provides critical evidence for the sophistication of Mississippian culture and its trade networks, which extended from the Gulf Coast to the Great Lakes.

About the site
Cahokia Mounds State Historic Site preserves the remains of the pre-Columbian Native American city that was the center of the Mississippian culture and the largest settlement north of Mexico. The city was occupied from about 600 to 1400 CE, reaching its peak population between 1050 and 1200 CE.
The site contains approximately 120 earthen mounds, of which 80 have been preserved. The mounds served a variety of functions including as platforms for temples and elite residences, as burial sites, and as markers of cosmological significance. Monks Mound, the central feature, rises in four terraces to a height of approximately 100 feet and covers more than 14 acres at its base — larger by volume than the Pyramid of the Sun at Teotihuacan.
The site was excavated beginning in the 19th century and has been subject to extensive archaeological work throughout the 20th and 21st centuries. Excavations have revealed that Cahokia had a planned urban layout, with the central plaza aligned on a precise north-south axis and mounds arranged in deliberate spatial relationships.
The population of Cahokia declined significantly after 1200 CE, and the city was largely abandoned by 1350–1400 CE. The causes of this decline remain debated among archaeologists and include environmental degradation, agricultural overextension, political instability, and climate change associated with the Medieval Warm Period.
