It is a barrow, a prehistoric burial mound, and its position feels deliberate, placed where the land gives way rather than where it rises. The mound is sub-circular in plan, measuring roughly thirteen metres across at its base, and rises to just over two metres at its highest point, though the surface slopes gently to the south-west. A shallow fosse, the encircling ditch typically dug when the material for a mound was gathered, rings the base, and there are two slight depressions in the mound's surface. Whether those hollows are the result of subsidence, earlier disturbance, or something else entirely, the notes do not say.

The mound appears to be made primarily of earth, though some stone is visible within it. It was recorded on the Cassini edition of the Ordnance Survey six-inch map as far back as 1920, marked with hachures in the cartographic convention used for earthworks of this kind. That it was recognised and mapped over a century ago suggests it was already understood as something ancient and significant, even if no excavation has since clarified who built it, or when, or for whom. Barrows of this general type are found across Ireland and date broadly to the Bronze Age, though without excavation it is difficult to say more than that about any individual example.
