A barely perceptible ring in the grass of the Curragh is easy to dismiss as a trick of the light, but the shallow circular fosse, a ditch dug to define and enclose, that traces a circumference of roughly 6.4 metres here marks something considerably older than the military training ground that now surrounds it. This is a ditch barrow, a low burial monument defined not by a raised mound but by the encircling depression left when earth was scooped inward or outward to mark a site. At just a metre wide and evidently very shallow, this particular example is subtle to the point of near-invisibility, partially overgrown and crossed by a footpath on its western side, with vehicle tracks cutting across its southern limits.

What gives the site an additional layer of interest is its immediate neighbour. The barrow sits directly east of a linear earthwork known locally as the Black Pig's Dyke, a name shared by several ancient boundary earthworks found across Ireland, typically associated with the late prehistoric period and thought to have served as territorial or defensive demarcations. The proximity of a burial monument to such a boundary feature is a recurring pattern in the Irish landscape, where the dead were sometimes placed deliberately at liminal or marked edges of territory. Two further circular features lie close by, one roughly 20 metres to the east-south-east and another approximately 5 metres to the south, suggesting this may originally have been a small cluster of related monuments rather than a solitary grave. Their status as barrows remains uncertain, but the grouping is suggestive. The site was identified from aerial photography taken in 1999, which remains one of the more reliable ways of reading earthworks that have been reduced, by centuries of grazing and occasional vehicle traffic, to the faintest of impressions in level ground.
