It turned out to be a disused quarry, almost certainly worked within the last few centuries, and that was more or less the end of the official interest in it.

When an inspector visited in 1984, the site was assessed and found to post-date AD 1700, which placed it outside the scope of any formal archaeological record. Quarries of this period were a practical feature of the Irish rural landscape, opened to extract limestone, sandstone, or other local stone for building walls, houses, roads, and field boundaries. Once exhausted or simply abandoned, they filled gradually with scrub and water or were absorbed into surrounding farmland. This one, sitting quietly in grazing pasture, left behind little more than the fact of its existence and a brief note confirming what it was not.
