New Jersey State Prison

The New Jersey State Prison (NJSP), formerly known as Trenton State Prison, is a state men's prison in Trenton, New Jersey operated by the New Jersey Department of Corrections. It is the oldest prison in New Jersey and one of the oldest correctional facilities in the United States. It is the state’s only completely maximum security institution, housing the most difficult and/or dangerous male offenders in the inmate population. NJSP operates two security units and provides a high level of custodial supervision and control. Professional treatment services, such as education and social work, are a priority at the facility.
