Founded in 1988, the O'Fallon Historical Society is dedicated to the preservation of the history of O'Fallon, Illinois and surrounding area. O'Fallon is located in St. Clair County on I-64 just east of St. Louis, Missouri.
Since 1996, the Society has operated a museum at 101 W. State St. in downtown O'Fallon. Located in the historic First National Bank building (erected in 1903 and remodeled to its current exterior appearance in 1922), the museum is staffed exclusively by dedicated volunteers and boasts two floors of exhibit and storage space.
The museum features permanent exhibits on local schools, railroads, mining, industry, sports, and military service. Two famous sons - artist Bernie Fuchs and Academy Award winning actor William Holden - are celebrated in permanent exhibits as well. Special rotating exhibits are displayed on a seasonal basis.
Highlights of the museum's collections include a coal stove manufactured in O'Fallon at the Eureka Stove Foundry, a 1940s voting booth used in O'Fallon Township, the recreation of an early O'Fallon school classroom, a large early 20th Century shaving mug and implement collection, an early coal mine telephone system, and much more.
