The monument overlooks the Owenkillew River valley, with views stretching westward to Lough Swilly some five kilometres away. To the south, beyond the valley, a range of peaks rises into the sky, whilst a northward extension of these mountains blocks the eastern horizon. Now deeply embedded in peat, the tomb sits within a raised mound measuring nearly 14 metres in length and 8.5 metres across.

The structure reveals the classic features of a wedge tomb, with the remains of an elaborate facade at its western end and a gallery formed by opposing sidestones and a backstone at the eastern end. The northern side preserves an intact line of five outer wall stones, their inner faces rising up to 45 centimetres clear of the surrounding bog. The southern outer walling is less complete, with only two stones visible midway along the monument’s length, and possibly a third stone near the backstone. Both lines of outer walling diverge sharply towards the west, where they would have originally connected with the facade. The gallery stones, all of uniform height, have their inner faces exposed to a depth of one metre, with the opposed sidestones set a metre apart.

The facade itself appears to have been about five metres wide originally, though only its northern half survives intact. This section consists of five stones arranged in an intriguing pattern; two pairs of stones set face to face, with a fifth slab spanning the gap between them on the outside. A solitary stone at the southwest corner represents all that remains of the facade’s southern portion. Archaeological evidence suggests the tomb may have been opened during the second half of the 19th century, though its original gallery length is estimated to have been between 3.5 and 4 metres. Despite its obscurity and the encroaching peat, this monument stands as a remarkable example of Ireland’s Neolithic architectural tradition, preserved in the boglands of County Donegal.
