Cahokia Mounds State Historic Site preserves the central section of the largest prehistoric Indian settlement in America north of Mexico. It covered nearly six square miles with 120 mounds and a population of 10-20,000 people of the Mississippian culture during its peak around AD 1050-1150. A world-class Interpretive Center/Museum tells the story of this great Indian city with dioramas, murals, graphics, artifacts,and a recreated village. It has an award-winning orientation show, an excellent gift shop, and a number of outdoor interpretive trails, and guided and self-guided tours. Visitors can also climb the 156 stairs to the top of 100-foot-high Monks Mound and visit the reconstructed Woodhenge sun calendar. Special events, programs, lectures, craft classes, and more are held throughout the year. The Interpretive Center is open seven days a week from May through October; from November through April it is closed on Mondays and Tuesdays.The grounds are open from 8 am to dusk.
