The site at Ballynacree is classified as a possible ring barrow, a type of funerary monument typically consisting of a low central mound surrounded by a circular ditch and outer bank, built to mark the burial of the dead during the Bronze Age. Nothing of that structure is visible today, which makes this one of the more quietly curious entries in the archaeological record of the county.

The site was not found by fieldwork or chance discovery but by scrutiny of aerial photography, specifically the Bruff aerial survey, reference 2029, as noted by Doody in 1993. Seen from the air, cropmarks or soil variations can reveal the ghostly outlines of buried features that have long since been levelled at ground level, and it was through exactly this kind of evidence that the possible monument at Ballynacree came to light. Its condition, however, is uncertain. A field drain running northeast to southwest across this part of the field may have cut through or otherwise disturbed whatever remains exist below the surface, complicating any future assessment of what survives. The wet, level terrain of the area, currently under pasture, adds a further layer of difficulty to interpreting the site.
