Her Majesty's Prison Maze (known colloquially as The H Blocks, Long Kesh, or The Maze) was a prison used to house paramilitary prisoners during the Northern Ireland Troubles from mid-1971 to mid-2000.
It is in the former Royal Air Force station at Long Kesh near Lisburn, nine miles (14 km) outside Belfast, in County Down, Northern Ireland. The prison and its inmates played a prominent role in recent Irish history, notably in the 1981 hunger strike. The prison was closed in 2000 and razing began on 30 October 2006, but has been halted.
