North Branch Correctional Institution (NBCI) is a high-tech, maximum security prison or "hyper-max prison" operated by the Maryland Department of Public Safety and Correctional Services in Cresaptown census-designated place, unincorporated Allegany County, United States,[1] near Cumberland.

[2] NBCI initially opened in January 2003 as an extension of the earlier adjacent Western Correctional Institution, with full independent operation beginning in the summer 2008 with the completion of housing unit construction.

[7] The prison was constructed using an "inverted fortress" style of building placement, with a master control tower sitting in the middle of a complex that is ringed with housing units and support structures.

The control tower is designed for maximum oversight with minimal staffing, requiring only two officers to maintain the entire security system.

[8] Cell door windows are made of ballistic-resistant glass to allow easier observation and to enhance officer safety.

The walls of the cells are coated with a high grade epoxy paint resistant to scratching, chipping and even acid.

The perimeter consists of 15 miles (24 km) of inwardly curved razor wire and motion sensors, as well as regular patrols and fence inspections.

[10] These inmates had allegedly been assaulted by North Branch staff shortly after transfer to the facility from nearby Roxbury Correctional Institution after being uncooperative and violent towards RCI officers.
