Montana State Prison
Montana State Prison, Correctional facility in Deer Lodge, Montana, United States.
Montana State Prison spans 68 acres and contains multiple security units for male inmates, with a capacity to house 1,600 individuals within its concrete perimeter.
The prison began operations in 1871 as Montana Territorial Prison, relocating to its current location in 1979 after outgrowing the original downtown Deer Lodge structure.
The facility implements rehabilitation programs focused on education, vocational training, and behavioral management to prepare inmates for their return to Montana communities.
Visitors must obtain approval before arriving at the prison, located at 700 Conley Lake Road, and follow strict guidelines regarding clothing and permitted items.
Under Warden Frank Conley's leadership from 1890 to 1921, inmates participated in construction projects, including road building and logging throughout the region.
