It measures just 5.5 metres across and rises only marginally above the surrounding ground, yet the earthwork encircling it, a combination of inner ditch and outer bank, marks it out as something deliberate, ancient, and almost certainly funerary in purpose. This is a ring barrow, a monument type associated with burial ritual in prehistoric Ireland, typically consisting of a central mound enclosed by a circular ditch, known as a fosse, and an earthen bank beyond it.

The site was identified by archaeologist Frank Coyne during survey work in the summer of 2010, in the townland of Ash Hill. Coyne recorded the fosse as roughly 1.5 metres wide, with an outer bank measuring 1.6 metres wide and standing about 0.2 metres above the level of the surrounding field, modest dimensions that speak to centuries of weathering and gradual erosion. Most notably, the bank is noticeably worn away at the south-east, where a gap of approximately 6 metres interrupts the otherwise continuous circuit. Coyne suggests this may preserve the position of the original entrance to the monument, a detail that, if correct, offers a faint echo of how people once moved through and around the site during whatever rites it was built to serve.

The ring barrow lies roughly 40 metres south of Greenfield Road, placing it in accessible but unremarkable agricultural countryside. There is no formal access or visitor infrastructure, and the mound's low profile means it rewards careful attention rather than a casual glance. The surrounding field is given over to pasture, so conditions underfoot will depend on the season and recent weather. The south-east gap in the bank is the most legible feature on the ground, and orienting yourself to that point gives the clearest sense of the monument's original geometry. As with many such sites recorded during development surveys, its significance lies less in spectacle than in what it implies, a community, a burial tradition, and a deliberate shaping of the land that has, against the odds, survived.
