HM Prison Maghaberry
prison in Lisburn, Northern Ireland

HM Prison Maghaberry is a high security prison near Lisburn in the south-west of County Antrim in Northern Ireland which opened in 1986. It was built on the site of RAF Maghaberry, a World War II airfield used as a flying station by the Royal Air Force and a transit airfield for the United States Army Air Forces. At the end of the war, the airfield was run down and was bought back from the Air Ministry in 1957 by Edward Thomas Boyes who then farmed it with his sons until the Northern Ireland Office (NIO) began work on the prison in 1976.
Mourne House, which held female prisoners, young offenders, and remands, was the first part to be opened, in March 1986. This followed the closure of the women's prison at HMP Armagh. The male part of the prison became fully operational on 2 November 1987. Following the closure of HMP Belfast on 31 March 1996, Maghaberry became the adult committal prison in Northern Ireland. Two new accommodation blocks were opened in 1999.
In 2003, the Steele report recommended options to make Maghaberry safe, including "a degree of separation" for Irish republican and Ulster loyalist inmates.
Maghaberry is currently a high-security prison housing both adult male long-term sentenced and remand prisoners in both separated and integrated conditions.
