The Williamson County Jail, located at 105 S. Van Buren St. in Marion, is the former county jail serving Williamson County, Illinois. The Prairie School building served as the county jail from 1913 to 1971. The jail housed prisoners involved with three violent conflicts in the 1920s: the Herrin mass
acre, the Klan War, and a gang rivalry between the Shelton Brothers Gang and Charles Birger's gang. The building is now a history museum and is listed on the National Register of Historic Places.
