Around 1050 CE the settlement at Cahokia, across the Mississippi River from modern St. Louis, expanded dramatically into the largest urban centre of pre-Columbian North America north of Mexico.
At its height between roughly 1050 and 1150 it covered about six square miles, contained some 120 earthen mounds, and housed an estimated 10,000 to 20,000 people, with many more in surrounding towns. Its centrepiece, Monks Mound, was raised in stages into the largest prehistoric earthwork in the Americas, about 30 metres tall, topped by a great timber building overlooking a vast plaza. Cahokia was the political and ceremonial focus of the Mississippian culture, whose maize-based chiefdoms, platform-mound towns and shared religious iconography spread across much of the central and southeastern present-day United States. A planned woodhenge of timber posts tracked the solar calendar. The city declined and was abandoned by about 1350 amid environmental stress and political fragmentation, but it demonstrates the scale of indigenous urbanism in North America and is recognised as a UNESCO World Heritage Site.
