World War II structures, To rear of 104 Greencastle Road, Kilkeel, Newry, Co Down, BT34 4JP

This group of eleven buildings formed the instructional site of Greencastle's Second World War aerodrome. They are located to the rear and southwest of 102 Greencastle Road and to the rear of 104 Greencastle Road.

Gunnery and Crew Procedure Centre

The largest structure on the site is the Gunnery and Crew Procedure Centre, positioned at the north of the group. This substantial building measures approximately 17 metres by 35 metres and is aligned northeast-southwest. It has a pitched corrugated asbestos cement roof with two large circular asbestos cement vents on each pitch. The rainwater goods are asbestos cement, though some sections have been replaced with metal. The walls are smooth rendered permanent red brickwork, 200 millimetres thick, with buttresses at regular intervals.

The southwest gable is five bays wide. The central bay contains a large pair of framed and sheeted painted timber sliding doors, with a wicket gate in the right-hand door. Each of the remaining bays has a blocked-up window opening. In the gable above the doorway is a pair of square louvred timber vents.

Each side elevation is eight bays wide. All bays have blocked-up windows except for the third bay from the left on the northwest elevation, which is wider and contains a pair of double-leaf sliding doors. The southeast elevation mirrors the northwest but its doorway has been infilled and buttressed at each end, now only two leaves wide.

The northeast gable is four bays wide with blank walls to the middle bays. Each end bay has a single blocked-up window opening. There are two vents in the gable apex matching those on the southwest gable.

Air Ministry Laboratory Bombing Teacher Blocks

The site includes a double Air Ministry Laboratory bombing teacher block positioned in the centre of the group, south of the Gunnery and Crew Procedure Centre. Further south is a similar single Air Ministry Laboratory structure. The remaining buildings are single-storey temporary brick structures used for various purposes.
