World War II Picket Post, Ballynahatten Road, Kilkeel

A much-altered small single-storey picket post aligned west to east in a field opposite 22 Ballynahatten Road. Dating from the 1940s, it represents austerity wartime architecture designed to minimise material consumption while maximising practical utility.

The building comprises two unequal bays constructed on a concrete plinth with temporary red brick walls (100mm thick), cement rendered and supported by buttresses at regular intervals. The original pitched corrugated asbestos cement roof has been replaced with a corrugated metal mono-pitched roof. Multiple doors and windows have been blocked up, including the main entrance on the right (narrower) bay of the west (road-facing) elevation. The north gable contains three bays, featuring a door to the left bay and a small blocked-up window to the right bay. The east elevation retains blocked-up paired casement windows to each of its two bays. The south gable has a blocked-up door positioned left of centre, flanked by single-paned windows positioned just below the eaves.

The picket post matches Air Ministry design number 14294/40, a typical design found on temporary wartime airfields. Though absent from the 1946 Air Ministry map of Greencastle Aerodrome, it reflects the dispersed utility construction strategy of the period.

Construction at Greencastle began in spring 1942 under contractor Carmichael of Edinburgh. Kilkeel RAF Station was commissioned on 30 July 1942 and handed to the United States Army Air Force on 3 August 1943, becoming Station 237, one of 12 American airfields in Northern Ireland. The station served as a satellite to Langford Lodge near Antrim, preparing aircraft for operational deployment in East Anglia and hosting a Combat Crew Replacement Centre from 20 December 1943 until autumn 1944. The base returned to RAF control on 31 May 1945 and was decommissioned shortly after, remaining in Air Ministry ownership until sale in the early 1960s. The building demonstrates the temporary nature of wartime military construction and possesses industrial archaeological interest.
