New Castle Correctional Facility is a privately run (but state-owned) prison located in New Castle, Indiana. It opened in 2002. In September 2005, the state signed a contract with the for-profit GEO Group, Inc. of Boca Raton, Florida, to run the prison. The facility is rated as minimum- to medium-security, but also has a maximum-security psychiatric unit and annex. After the annex was opened, it became the largest prison in Indiana, and can hold over 3,500 inmates.
