The O'Fallon Historical Society was organized in 1974 to preserve and protect O’Fallon’s history for future generations. We meet four times a year at the Society’s Log Cabin Museum in Civic Park on the first Monday of each quarter: March, June, September (on the 2nd Monday due to Labor Day), and December. The December meeting is the traditional Christmas dinner and program. Be sure to visit our Gift Shop and see how you can purchase a copy of O’Fallon: A Good Place to Live, as well as the Historical Society’s annual Calendar featuring vintage photos of O’Fallon’s historic scenery.
