The Montana State PRison is an exclusive men’s only state prison. The Montana State Prison is a part of the Montana Department of Corrections. The Montana State Prison is nestled in the unincorporated part of Powell County, Montana just 3.5 miles away from Deer Lodge.

The facility that is in use now was build from 1974 to 1979. This new facility was built because of the degeneration of the old building. The old Montana State Prison was nested in downtown Deer Lodge.

The old Montana State Prison purpose was to be the Montana Territorial Prison. It was built in 1871 and was in use until Montana received its statehood later in 1889. The Montana State Prison then primary duties was as a penal institution for Montana until 1979.

Throughout the years of the Montana State Prison history, the prison was commonly overcrowded, lacked funds, and didn’t have adequate facilities. Warden Frank Conley during his time he made sure that inmates had extensive projects that would help the facility, such as constructing walls, building roads, ranching, and various other community service tasks.

When Conley left as warden of Montana State Prison, the facility went for nearly 40 years of degeneration, monetary restraints, and mismanagement. This was until the well-known riot that happened in 1959. This riot caught the national news. The riot was led by Lee Smart and Jerry Myles. The riot lasted for 36 hours before the Montana National Guard came in to stop it.

In 1979, the original old facility closed its doors and all of the inmates were moved over to the new facility. However, the original old prison was added in 1976 to the National Register of Historic Places. It is currently a museum.

When the Montana State Prison first opened its doors, it only took a month before the facility was overcrowded. This persisted throughout many years, but it really reached its peak in 1885.
