This one offers none of that. Somewhere in a field of reclaimed pasture in Bohercarron, on the very edge of County Limerick where a small watercourse quietly separates it from County Tipperary, there may be a prehistoric barrow, a burial mound of the kind raised across Ireland during the Bronze Age and earlier, now so thoroughly absorbed into the agricultural landscape that it leaves no visible trace at the surface whatsoever.

The site came to light not through excavation or fieldwork on the ground but through the sky. An aerial photographic survey centred on the Bruff area, carried out in 1986, picked up what appears to be a circular cropmark consistent with a barrow, recorded under the reference Bruff 18.02 and aerial photograph AP 5/2133. Cropmarks form when buried features, such as filled-in ditches or compacted earthworks, cause the vegetation or soil above them to behave differently from the surrounding field, a difference visible from altitude even when nothing can be seen at eye level. The possible site sits roughly 75 metres west of the watercourse that doubles as a townland boundary between Bohercarron and Ballywire, and a second possible barrow has been identified approximately 15 metres to the northwest. Neither feature appears on Ordnance Survey Ireland historic maps, and more recent Google Earth orthoimages show no surface remains at all.

There is, in practical terms, very little to see here, and that is precisely what makes this record worth knowing about. The monument has a provisional classification only, carrying no confirmed monument number, and the landscape has been so thoroughly worked over by generations of farming that the mound, if it was ever a mound, is gone. Anyone with a serious interest in the area would do better to start with the aerial photograph held under the Bruff survey reference, or to consult the National Monuments Service record, than to search the pasture itself. The real interest lies in what the 1986 survey revealed about how much archaeology lies beneath ordinary-looking farmland along the Limerick and Tipperary border, invisible from the road, unmarked on any map, and known only because someone thought to look from above.
