This is a ditch barrow, a type of prehistoric funerary or ritual monument defined not by a raised mound but by a surrounding fosse, the term used for a dug ditch or trench. The fosse here traces an almost perfectly circular path, measuring roughly 5.25 metres north to south and 5.1 metres east to west, with a channel about 1.75 metres wide and only five centimetres deep at its base. Modest in scale, it is the kind of monument that survives precisely because it asked so little of the landscape around it.

The site came to light on 17 February 2009, when archaeologists Alison McQueen and Vera Rahilly identified it during field survey work. What makes its position particularly notable is that it does not stand alone. It abuts a ring-barrow directly to the west, a related but distinct monument type in which a low earthen mound is enclosed by a ditch and sometimes an outer bank. A further enclosure sits approximately 25 metres to the south-west. This loose clustering of monument types on a single slope is characteristic of how prehistoric communities used landscape, gathering burial and ceremonial sites into loose groupings over long periods rather than constructing them in isolation. The eastern edge of the fosse has suffered some minor damage from a land drain running along a field boundary, a small modern intrusion that is a common hazard for low-lying earthworks across Ireland.
