By 1837, when the first detailed Ordnance Survey maps were drawn up, it was recorded simply as a burial ground, a rectangular enclosed area of roughly twenty by thirteen metres. By the 1893 revision, something had shifted in local imagination: the site had acquired the name "Giant's Grave", one of those recurring placename types found across Ireland that signals a community reaching for a mythological explanation of something ancient and unexplained underfoot.

The mound itself is oval in shape, about fourteen metres by ten metres, and rises to a modest height of less than a metre. Two pillar-stones stand upright within it, one of them a cross-inscribed slab with a cross set within a circle, a form associated with early Christian memorial tradition. A standing stone marks the south-western end. About forty yards to the west, two small stone cairns, each roughly five metres across and less than a metre high, add to the cluster of features without clarifying what they belong to. Ruairí de Valéra and Seán Ó Nualláin, who surveyed megalithic monuments across Ireland in the mid-twentieth century, examined the site in 1964 and concluded, with measured directness, that there was no reason to assume a megalithic tomb had ever existed here. The mound, in other words, is probably not a passage tomb or court cairn in the recognised prehistoric tradition, even if its profile and the stones it contains suggest something deliberate and commemorative.

What remains is a site that resists easy classification: neither a confirmed prehistoric monument nor a straightforward post-medieval burial enclosure, but an oval rise in the ground holding two ancient stones, one of them marked with a Christian symbol, the other a plain upright, and a folk name that arrived late but has stuck.
