A souterrain, which is a man-made underground structure typically built from dry-stone walling and used in early medieval Ireland for storage, refuge, or concealment, is usually the kind of discovery that brings construction to a halt. In this case, it did not.

Around 1977, during the building of a house, workers broke through what local accounts described as a stone-lined passage. Before any formal investigation could take place, the foundation trenches had already done their damage, and the structure was destroyed. What survives is only a secondhand account, passed along by a local contact identified as S. Lane. No dimensions were recorded, no photographs taken, no artefacts recovered. The souterrain exists now only as a line in an archaeological inventory, a brief notation of something that was there and then, very quickly, was not.
