Her Majesty's Prison Maze (previously Long Kesh Detention Centre, and known colloquially as The Maze or H-Blocks) was a prison in Northern Ireland that was used to house paramilitary prisoners during the Troubles from August 1971 to September 2000. It was situated at the former Royal Air Force station of Long Kesh, on the outskirts of Lisburn. This was in the townland of Maze, about southwest of Belfast. The prison and its inmates were involved in such events as the 1981 hunger strike. The prison was closed in 2000 and demolition began on 30 October 2006, but on 18 April 2013 it was announced by the Northern Ireland Executive that the remaining buildings would be redeveloped into a peace centre. Background Following the introduction of internment in 1971, Operation Demetrius was implemented by the Royal Ulster Constabulary (RUC) and British Army with raids for 452 suspects on 9 August 1971. The RUC and army arrested 342 Irish nationalists, but key Provisional Irish Republican Army (IRA) members had been tipped off and 104 of those arrested were released when it emerged they had no paramilitary connections. Those behind Operation Demetrius were accused of bungling, by arresting many of the wrong people and using out-of-date information. Following nationalist protests, some Ulster loyalists were also arrested. By 1972, there were 924 internees and by the end of internment on 5 December 1975, 1,981 people had been detained; 1,874 (94.6%) of whom were Catholic/Irish nationalist and 107 (5.4%) Ulster Protestants/loyalists. Initially, the internees were housed, with different paramilitary groups separated from each other, in Nissen huts at a disused RAF airfield that became the Long Kesh Detention Centre. The internees and their supporters agitated for improvements in their conditions and status; they saw themselves as political prisoners rather than common criminals. In July 1972, the Secretary of State for Northern Ireland, William Whitelaw introduced Special Category Status for those sentenced for crimes relating to the civil violence. There were 1,100 Special Category Status prisoners at that time. Special Category Status for convicted paramilitary-linked prisoners gave them the same privileges previously available only to internees. These privileges included free association between prisoners, extra visits, food parcels and the right to wear their own clothes rather than prison uniforms. However, Special Category Status was short-lived. As part of a new British policy of "criminalisation", and coinciding with the end of internment, the new Secretary of State
