During The Second World War, those tasked with home defence erected a line of wooden obstacles along the beach to make life difficult for any would-be invaders.
In the early stages of the war, Northern Ireland prepared for an enemy invasion. Among the provisions were a series of wooden beach defences along stretches of the Co. Down coast. Parts of these structures remain near the village of Dundrum.
Pillboxes once maintained a lookout along parts of Northern Ireland's coastline. Only fragments of concrete remain partially buried in the sand at Murlough Bay in Dundrum, Co. Down.
