It is a barrow, a prehistoric burial mound, and at first glance it could easily be dismissed as a natural undulation. The circular earthwork measures roughly sixteen metres north to south and seventeen metres east to west, defined by a broad, low bank with a gently rounded profile. At its most pronounced, on the western side, the bank stands only 0.65 metres above the surrounding ground on its outer face. Inside, a faint circular rise of about two metres across sits at the centre, barely discernible beneath the turf. The whole thing is so subtle that a person crossing the field might never notice it.

Barrows of this kind are among the oldest human-made features in the Irish landscape, typically associated with Bronze Age burial practices, though their precise dates vary considerably without excavation. This particular example sits in a quietly dramatic setting. The mouth of a river enters the sea about a hundred metres to the west, at the centre of the cove. To the east, on the horizon, the great bulk of Knocknarae is visible, the hill above Strandhill that carries the massive cairn of Medb's supposed tomb on its summit. To the south-east, the Ox Mountains close off the skyline. Whoever chose this spot was placing the dead in a landscape already charged with meaning, at the edge of water and within sight of monuments that were perhaps already ancient. The barrow itself has not escaped later interference entirely: a dry-stone field wall, 0.9 metres high and running on a north to south axis, cuts directly through the eastern edge, a reminder that farming has been reshaping these sites for centuries. A few stones protrude unevenly from the sod on the bank, particularly at the west and north-west, suggesting that the mound may once have had a more structured internal core.
