It does not appear on Ordnance Survey maps from 1838 or 1922, yet it has long carried a name: locally it was known as Dermot and Grania's Bed, a title given across Ireland to megalithic monuments associated with the lovers Diarmuid and Gráinne, fugitives from the mythological Fianna. The name says less about the monument's actual origins than about how rural communities made sense of ancient structures before formal archaeology gave them a different kind of identity.

The tomb is classified as a National Monument, designated No. 293 and in state care, though its precise type within the broad family of megalithic tombs, large stone burial chambers built during the Neolithic period, remains unresolved. An early twentieth-century record from the Office of Public Works described a grave measuring roughly 3.6 metres by 1.5 metres, oriented northwest to southwest, with its right-hand side stones still standing: two at the western end, four along the southern side, two at the eastern end. Two further stones lay about three metres to the east. By 1996, when the site was formally inspected, the structure had reduced to a stony mound roughly four metres across its longest axis and just over a metre in height, with one large boulder still visible near the southern edge. The field fence that had encroached on its northern side was by then its most prominent neighbour.
