The mound was small, only about eight metres across, and it did not appear on any Ordnance Survey sheet. Yet the find beneath it quietly pointed to something older and quite different.

A mound barrow is a prehistoric funerary monument, essentially a raised earthen mound covering one or more burials, and the distinction from a ringfort matters considerably. Ringforts are early medieval enclosures, typically used as defended farmsteads, while mound barrows belong to a much earlier tradition of burial, often dating to the Bronze Age. The ESB's initial misidentification was understandable given the site's absence from maps, but a sketch section drawn up by Mr Bart Bambury of the ESB and passed on to Marcus Ó hEochaidhe of the National Monuments Service, combined with the modest eight-metre diameter, pointed researchers towards the barrow interpretation. Two or three skeletons were found at a depth of between thirty centimetres and forty-five centimetres below the surface. The bones were described at the time as belonging to young men, and notably their teeth were in good condition. Construction work in the area was stopped to allow for examination, though the site was never formally excavated and the remains were not taken into any institutional collection. What became of the bones after that is simply not recorded.

The site sits in the townland of Aghanashanamore and remains something of an administrative loose end, officially listed in the Sites and Monuments Record only as a ringfort. The people buried there, the circumstances of their interment, and the precise age of the mound have never been established.
