Mississippian culture, the last major prehistoric cultural development in North America, lasting from about ad 700 to the time of the arrival of the first European explorers.
The scale of public works in the Mississippian culture can be estimated from the largest of the earthworks, Monks Mound, in the Cahokia Mounds near Collinsville, Illinois, which is approximately 1,000 feet (300 metres) long, 700 feet (200 m) wide, and 100 feet (30 metres) high.
