This ring barrow, a low circular earthwork typically consisting of a central mound surrounded by a ditch and outer bank, was used for burial during the Bronze Age, and examples are scattered across Ireland in varying states of preservation. What makes this particular one quietly remarkable is that it does not appear on the Ordnance Survey maps at all. It exists, in the official cartographic record, not quite as a place.

The barrow came to light not through ground survey but from the air. During a 1986 aerial photographic survey centred on Bruff, photographers captured what is recorded as a circular cropmark at this location, catalogued as reference Bruff 55, AP 4/3683. Cropmarks appear when buried or eroded archaeological features influence how crops or grass grow above them, producing patterns visible from altitude that are invisible at ground level. A companion monument, registered as LI024-152002-, lies about 15 metres to the south, suggesting this was once part of a small cluster of funerary features rather than an isolated burial. The site sits in pasture roughly 15 metres west of the stream that marks the townland boundary between Boherroe and Killeenaverra. Decades after the 1986 survey, a circular cropmark was still visible in the north-east corner of the field on a Google Earth orthoimage dated 28 June 2018, confirming that something beneath the soil continues to leave its faint trace on the surface.

Because the monument is in private agricultural land and shows no upstanding remains, there is little to see from a public road without prior knowledge of what to look for. The cropmark effect is most pronounced during dry summers, when differential moisture retention in the soil above buried features draws contrasting patches of growth across an otherwise uniform field. Anyone with a serious interest would do well to consult the National Monuments Service record and contact the landowner before visiting. The location near the Boherroe and Killeenaverra townland boundary provides the clearest navigation point, and the stream itself serves as a useful marker for orienting within the landscape.
