Cahokia, IL Area Guide

Cahokia traces its founding to 1699, when missionaries from Quebec established a mission here, making it one of the oldest European settlements in Illinois. The Church of the Holy Family, built between 1786 and 1799, is said to be the oldest continuously active Catholic parish in the United States and the oldest church building west of the Allegheny Mountains, and it's a National Historic Landmark. Nearby, the Cahokia Courthouse State Historic Site is a reconstructed French-Canadian structure built around 1740, and the Jarrot Mansion (built 1807–1810) is one of the oldest brick homes in Illinois. n 2021, Cahokia's village government dissolved into the newly formed city of Cahokia Heights, ending its status as an independent municipality while its historic core remains one of the most distinctive parts of the region.
