By 1937, the Ordnance Survey recorded it as a small hachured mound, the kind of symbol cartographers used to indicate a raised earthwork of some kind. Today even that modest prominence is gone, levelled at some point in the intervening decades, leaving only a sunken outline and a scatter of stones across the ground.

What the mound originally represented is not entirely clear. One possibility, suggested by the stones and the context, is that it was a lime kiln, a structure once common across the Irish countryside, where limestone was burned at high temperatures to produce quicklime for agricultural use in sweetening acidic soils. A quarry sits in the same field to the south, which would fit neatly with that interpretation, as raw material would have been close at hand. Whether the mound had any earlier origin before being repurposed or simply built over is unknown. The archaeological record offers a feature that has been reduced to an absence, a place defined more by what is no longer there than by what remains.
