The Kosciusko County Historical Society (KCHS) was founded in 1966 and is a non-profit corporation dedicated exclusively to the research, preservation, and teaching of the history of Kosciusko County.
The Old Jail Museum and Research Library are open to the public 24 hours a week throughout the season from March through mid-December, with additional hours by appointment.
We preserve artifacts from the county and use rotating displays in the museum. We offer scheduled tours for school children, individuals, families, organizations, and clubs.
The KCHS also sponsors special events such as the Dillinger Raid, Historic Tours, Oswego Trader Days, Gingerbread Extravaganza, Historic Landmarks, Boice Films, Kiosk, Chinworth Bridge, the Pound Store, and others.
