Others exist almost entirely as an idea, a faint signature read from the air rather than the ground. In a pasture in Baunnageeragh, on the southern edge of a townland boundary with Ballynamona in County Limerick, there is a site that belongs firmly to this second category. Classified as a possible barrow, it leaves no surface trace whatsoever visible on satellite imagery, and it never made it onto the Ordnance Survey's historic maps. Its existence rests, for now, on a single aerial photograph and the trained eye of one person who knew what to look for.

A barrow, in the Irish archaeological context, is a burial mound, typically dating from the Bronze Age or earlier, constructed to mark and contain the remains of the dead. They range from substantial earthen monuments to subtle ring-shaped cropmarks that only emerge under particular light and seasonal conditions. This particular site was identified by Katherine Daly during a systematic aerial photographic survey centred on the Bruff area in 1986, the relevant image catalogued as Bruff AP 5/2115. Daly flagged it as a possible barrow, a careful designation that signals potential rather than certainty. What makes the location quietly interesting is its company: two further possible barrows sit within thirty metres of it, one approximately twenty-five metres to the west and another around thirty metres to the southwest, suggesting this corner of south Limerick may have once held a small cluster of funerary monuments, though none of them is confirmed and all three remain below the threshold of cartographic recognition.

For anyone inclined to visit, the honest reality is that there is nothing physically to see. The site sits in ordinary agricultural pasture, and current satellite imagery shows no crop or soil marks distinguishing it from the surrounding land. Its interest lies in the question it poses rather than any feature it presents. The aerial photograph held in the Bruff survey archive remains the primary evidence, and the record as compiled by Martin Fitzpatrick and uploaded in June 2021 holds the essential detail. Anyone with a serious research interest would do better to start with that documentary record than to walk the field itself, where the monument, if it exists, keeps its own counsel entirely underground.
