Celebrate O’Fallon, Illinois and it’s history through the first annual Founders’ Day event! 168 years ago, almost to the day, a parcel auction was held very near the current O’Fallon Station. The town lots auctioned helped create our current downtown O’Fallon. In honor of that, we are recreating the auction and selling O’Fallon experiences, proceeds to benefit the O’Fallon Historical Society. Additional activities include horse and trolley rides, a championship pie bake off contest and historic kids games like hoop and stick and sack races. Don’t miss this celebration, it is sure to be a blast from the past!
