Fort de Chartres
Located south of St. Louis near Praire du Rocher, Illinois, this fort was first built by the French in 1720 during their eighteenth-century colonization of the area. Due to its location in the floodplain of the Mississippi River, it had to be rebuilt twice. What's left of the limestone iteration, originally built in 1753, is considered the oldest building in the state of Illinois. The rest has been partially reconstructed and offers a glimpse into the area's past.
Another snapshot of French colonialism in the region can be found in Missouri's oldest town, Ste. Geneviève. Settlers from France, Canada, and other French-held territories settled in this spot along the Mississippi river in 1735. The distinct French Creole colonial architecture and culture have been well-preserved in museums and throughout the historic downtown.
Right across the Mississippi from St. Louis is the site of a Native American city which at one time was among the most populous metropolises in the world, even exceeding London. The name of the historic site refers to the awe-inspiring manmade earthen mounds which were built by the Mississippian people of Cahokia. Visitors can still see some of these mounds on the site, as well as a Museum & Interpretive Center.
