Monks Mound

Monks Mound is a large, ancient earthen structure at Cahokia Mounds in Illinois, built by Native Americans around 1050-1350 AD. It is the largest prehistoric earthwork in North America, standing about 100 feet high, covering around 14 acres. The mound served as the platform for a important chief’s residence or temple, symbolizing social and spiritual power. Its construction involved thousands of people moving and shaping huge amounts of earth. Today, Monks Mound offers insights into the complex society and advanced engineering skills of the Cahokia civilization.
