Michigan State Prison (also called the Jackson Prison) was the first state prison, built in 1842. A larger prison building was built in 1926 and used until 2007. It was reorganized into separate prisons in 1988. The Detroit House of Corrections, built in 1861, was owned and run by the city of Detroit but originally accepted prisoners from throughout the state including women. The Detroit House of Corrections was transferred to the state in 1986, renamed to Western Wayne Correctional Facility, and became a women's facility for the rest of its tenure. It eventually closed in December 2004 and all inmates and staff were transferred to the Huron Valley Complex in Ypsilanti. The closure of the facility saved the state an estimated $23 million per year. The Michigan Asylum for Insane Criminals was built in Ionia in 1885 and treated prisoners and non-prisoners until 1972. It was renamed the Ionia State Hospital before being the Riverside Correctional Facility until Riverside was closed in 2007. The Marquette Branch Prison was built in 1889 for Upper Peninsula prisoners and the original building is still in use.
