What makes the structure quietly interesting is not simply its state of decay, but what it once was and what it sits beside: the northern end of the building is formed by a limekiln, a stone furnace once used to burn limestone into quicklime for agricultural and building purposes. The two functions, coast guard surveillance and lime production, share a wall.

The 1842 Ordnance Survey six-inch map labels the site as a Coast Guard Station, placing its active life firmly in the early nineteenth century, a period when the British coastguard service maintained a close network of small outposts along the southern Irish shore, primarily to intercept smuggling and monitor maritime traffic. The building's position, constructed against a natural slope and looking out over the cove, would have given those stationed there a clear line of sight to the water below. Inside, the surviving internal divisions suggest the ground floor was arranged into three rooms, a modest but functional layout consistent with a small operational outpost rather than a substantial barracks. The attachment of a limekiln at the northern end hints at the practical, self-sufficient character of such remote stations, where the boundary between a working building and the surrounding agricultural economy was often blurred.
