Hangars (former aircraft assembly hangars), Gate 3, Maze, Long Kesh, 94b Halftown Road, Lisburn BT27 5RF

These comprise two large steel framed Type 2 hangars aligned north south with low single storey red brick extensions between and to the east and a single and two storey red brick extensions to the west. Both hangars are of similar construction comprising 23 bays defined by ‘British Steel, Colville’ ‘U’ shaped channels with angle bracing between, supporting pitched trusses of similar construction. The columns are supported in pairs on concrete capped brick plinths, between which are doors linking through to the extensions. It was noted that the remains, in the form of footprint scar and bolts, of earlier columns survived between the existing columns implying an earlier upper structure. Large three leaf sliding doors survived to the north and south of both hangars with small wicket doors, tracks and projecting upper door rails to each building. The north doors of buildings 8 and 9 were fixed shut by the addition of an internal poured concrete plinth wall. The floor in both hangars was concrete with no clear evidence of fixing or earthing points or demarcation. The side walls of both buildings comprised brick lower elements with stone copings, on which sat a metal flashing and large timber windows within a steel angle frame. The roofs appeared to be of a corrugated mineral sheeting board. The open plan area of building 8 had been partially subdivided by the insertion of concrete panels and fences to create a mock prison scenario. This area had been used for siege, riot and general officer training. In the southeast corner of the building were two modern porta-cabins providing officer accommodation and facilities (plumbed in to the former toilets) and a single cabin for chief officer and training.
