The Indiana Boys' School (IBS) was opened in 1867 as a correctional institution for adolescent boys. It was located on U.S. Route 40 just outside Plainfield, Indiana. For 138 years, it was the primary correctional facility for juvenile males in Indiana, situated on 1,038 acres. For most of its existence, it was a self-sustained institution, providing vocational training to the inmates in many different occupations, including agriculture, electrical, cooking, tailoring, barbering and shop work. In October 2005, the grounds and building were transformed into a pre-release center for adult males, while the boys were transferred to a new facility located on the grounds of the Indianapolis Juvenile Correctional Facility in west Indianapolis. IBS was a state operated, medium to maximum-security facility with approximately 245 staff and 335 boys housed in campus style cottages.
