Compound 19, Zone E1, The former Maze Prison, Halftown Road, Lisburn, BT27

Compound 19 at the former Maze Prison, Halftown Road, Lisburn, represents a typical arrangement of accommodation found in the prison's enclosure compounds. It demonstrates the facilities provided for politically motivated prisoners during the final phase of the Maze's expansion in January 1973 (Phase 6), as well as its earlier use as the Long Kesh Internment Centre.

The compound comprises an enclosed rectangular area of hard-standing tarmac, defined by a high weldmesh fence mounted on a low concrete plinth wall. The fence is divided into sections by timber posts topped with street lamps. The compound is aligned south-west to north-east, with open ground to the north (formerly Compounds 18 and 17). To the west lies the former internment camp perimeter fence, and beyond that a tall concrete dividing wall separating the Maze Compounds from the Maze Cellular. Compound 20 is situated approximately 8 metres to the south. The northeast corner features a gated air lock entrance; a Prison Service Staff Hut formerly stood outside the fence here but no longer survives.

The buildings form a coherent group at the compound's west end. Three full-length Nissen Huts (E1/3–5) are positioned to the north of a three-quarter-length Nissen Hut (E1/6). To the east stand a timber crafts hut (E1/7) and a timber ablutions block (E1/8).

The Nissen Huts employ simple steel rib construction clad with inner and outer corrugated sheet coverings. The three full-length dormitory huts have six dormer windows fitted with external bars and timber casements along each side; the three-quarter-length hut has five dormers per side. All huts have timber double doors at each end, some with timber porches.

The ablutions block is a vertical-sided timber hut built on a concrete slab, with high-level timber casements on its principal elevations and doors at each end. An elevated water tank on a timber support frame stands at the south end.

The crafts hut is a terrapin-type structure clad in horizontal timber boarding, elevated on concrete blocks, with a timber door at one end and timber casements along its elevations.

The structures themselves are of generic type and may predate their 1971–72 arrangement here. They are of interest as an intact group complemented by their setting of security fences and hard-standing. The interiors of the huts were altered to individual tastes by their occupants, and the use and internal arrangement of the crafts hut or kitchen/gym hut was determined by occupants. A fire in 1974 did not affect this compound. The prisoners accommodated in the compounds changed through frequent rotation, though only inmates affiliated to one political movement were housed at any given time.
