      Cahokia Mounds is currently the only UNESCO World Heritage site in Illinois. What we see today is the underpinnings of what was once the largest city in North America, the center of a thriving and complex culture that existed here from about 700 CE to the mid-1300s.

      Cahokia Mounds lies at the center of the broadest part of the American Bottom, a fertile ridge and swale topography created by the shifting bed of the Mississippi River since the retreat of the last glacier. With the Mississippi River just 5 miles to the west and the confluences of the Missouri River and the Illinois River to the north, this region provided abundant opportunities to establish extensive routes for the exchange of goods and culture. There has been human settlement in the American Bottom since at least 9500 BCE.
