It is a pond barrow, a type of prehistoric funerary or ritual enclosure characterised by a central depression rather than the mound you might expect from a burial monument. Where a round barrow rises from the ground, a pond barrow sinks into it, the hollow held within a surrounding bank, giving the whole thing an inverted, slightly counterintuitive quality that archaeologists have never fully explained. This particular example sits close to the top of a ridge known locally as Oileán na crú, at around 680 feet above ordnance datum, with two ringforts, the circular earthwork enclosures common across early medieval Ireland, sitting just 15 metres and 70 metres to the north and north-east respectively.

The monument was recorded by O'Dwyer in 1960 with a reasonable degree of clarity. At that point it presented as a platform roughly 30 feet in diameter, enclosed by a bank about five feet wide, then a ditch of similar width, then a second outer bank beyond that. On the east side, both banks and the ditch were interrupted by a gap of around six feet, forming a well-defined entrance onto the central platform. By the time the Archaeological Survey of Ireland came to survey it in 2007, the picture was considerably less legible. The monument was described as a poorly preserved oval-shaped depression, measuring roughly 6 metres north-north-east to south-south-west and 8 metres east-south-east to west-north-west, with only traces of a possible bank surviving to the north-north-east and east. The Ordnance Survey 25-inch map had shown a sub-circular enclosure intersected at the south-west by a trackway running north-west to south-east, and the outline of the depression enclosed by a bank remained visible on aerial imagery as recently as November 2018.

The site lies in reclaimed pasture, which means the ground underfoot will likely give little away. There is no signage, no formal access, and the earthworks themselves are subtle enough that knowing what you are looking for matters considerably. Aerial photographs taken by the ASI in August 2000 and January 2003 give the clearest sense of the monument's shape, and consulting these before a visit would help orient anyone approaching on the ground. The proximity of the two ringforts makes this a landscape worth reading slowly, with a cluster of monuments suggesting this ridge carried some significance across different periods, even if the specific nature of that significance has not been preserved along with the earthworks.
