The monument sits in a vast expanse of bogland, roughly 30 metres west of the Meenahonor Burn, a tributary that eventually flows into Trawbreaga Bay. When the tomb was first uncovered, workers also discovered the remains of a stone circle about 100 metres to the west, suggesting this remote area once held significant ritual importance for prehistoric communities.

The structure itself is a gallery tomb measuring at least 4.5 metres in length, oriented roughly west to east, with the characteristic wedge shape that gives these monuments their name; wider and taller at the western entrance, gradually narrowing and decreasing in height towards the east. The gallery, now open at both ends due to centuries of deterioration, is flanked by outer-walling stones and retains a single roofstone positioned roughly midway along its length. The roofstone, measuring 1.45 metres north-south by 1.1 metres east-west, has slipped from its original position but still provides a glimpse of how the tomb would have appeared when intact.

Archaeological surveys conducted in 1982 and 1991 revealed the monument’s complex construction, with orthostats of varying heights forming the gallery walls; the tallest standing 0.8 metres at the western entrance, while others barely protrude above ground level. The tomb appears to have been in ruins long before the peat gradually enveloped it, and whilst no trace of a cairn or mound remains, the scattered stones around the site hint at the monument’s former grandeur. Today, despite being partially concealed by discarded turf sods and never appearing on any Ordnance Survey maps, this wedge tomb stands as a remarkable testament to Ireland’s Neolithic past, preserved by the very bog that hid it from view for thousands of years.
