What is the oldest prison still active in the US?
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. The Bureau of State Use Industries operated the bedding and clothing shops that were once located in Shop Hall at the facility. These industries have been relocated to South Woods State Prison.
Walnut Grove Correctional Facility
The 'Walnut Grove Correctional Facility', formerly the 'Walnut Grove Youth Correctional Facility' (WGYCF), was operated as a for-profit state-owned prison in Walnut Grove, Mississippi from 1996 to 2016. Constructed beginning in 1990, it was expanded in 2001 and later, holding male youth offenders. It had an eventual capacity of 1,469 prisoners, making it the largest juvenile facility in the country. Contracts for the facility's operations and services were among those investigated by the FBI in its lengthy investigation of state corruption known as Operation Mississippi Hustle.
