Maine State Prison

Maine State Prison (MSP), located in Warren, is Maine's maximum-security facility. The residents are classified as close and medium custody. MSP, like MCC, is a receiving facility but for specific residents, those whose sentence exceeds five years, have escape convictions or known escape attempts from a medium or higher security facility, have special needs such as severe mental or emotional health or physical disabilities which pose a threat to themselves or other residents, and those who have been released within the last three years and at the time of release were classified as close custody. MSP also houses the Department's Intensive Mental House Unit.
