The Maximum Security facility is the state's oldest operational prison. The facility was opened during 1878 and is modeled on the Auburn style of construction, consolidating all inmate cells into one main building.

The facility was originally designed to house 252 inmates. Due to a growth in population, an addition was built in 1924 consisting of two cellblocks and 198 cells which became known as "steel city."

Maximum Security once served as the state's prison for both awaiting trial and sentenced inmates. As the sentenced population grew and the needs of the prison system changed, other facilities were added.

Surrounded by a wall with observation towers and a double chain-link security fence equipped with an electronic intrusion detection system to prevent and detect escape attempts, the facility is divided into six housing areas, one segregation unit, kitchen/dining area, recreation yard, education/gym building, and an industrial area.

Maximum Security employs over 230 inmates, approximately 59% of its total population. Inmates perform a variety of functions to help maintain the institution. Approximately 190 inmates work in areas such as the kitchen, laundry, barber shop, library, and as porters within the housing modules and recreation areas. Industries consists of a print shop, carpenter shop, and laundry.
