The structure is a ditch barrow, a type of prehistoric funerary monument in which a low, shallow ditch, or fosse, encloses a circular interior rather than a raised mound. This particular example measures just four metres in diameter, with a fosse roughly 1.6 metres wide and only about ten centimetres deep at the time of inspection. The interior is level and clear of overgrowth, which is part of what makes such features legible in the landscape at all.

What gives the site its quiet significance is not this one barrow alone, but its place within a wider cluster of monuments spread across the surrounding pasture. Six further prehistoric barrows lie within roughly 85 metres of this one, a mixture of ring-barrows, in which a bank rather than a ditch defines the enclosure, and other ditch barrows. Together they form a small barrow cemetery, a grouping that suggests this stretch of gently rolling ground was used over some period in prehistory as a dedicated place for the dead. Such cemetery groupings are known from across Ireland and Bronze Age Europe more broadly, where repeated burial in the same general area seems to have served social or territorial purposes as much as purely ritual ones. The site at Ballynaveen was identified through field inspection rather than aerial survey or excavation, meaning much of what lies beneath the surface remains unknown.
