Located nearly 5 kilometres west-northwest of Glenties village and 2 kilometres south of Gweebarra Bay, this megalithic monument offers views eastward along a boggy valley across Lough Ananima to the distant mountains. The tomb sits within a subcircular mound measuring roughly 11 metres across, though its outline has become somewhat obscured over the millennia, particularly on its western side where a later drystone enclosure was built incorporating the tomb into its eastern wall.

The chamber itself, which originally opened towards the south-southeast, has suffered considerable damage over time but enough remains to understand its original structure. The backstone at the north-northwest end remains in place alongside an adjacent sidestone, whilst the portal stones that once framed the entrance have partially collapsed. The eastern portal stone broke from its base at some point, with its upper portion now leaning against its western counterpart, which has pitched over against the old sheephouse wall. When intact, these portal stones would have stood approximately 1.7 to 1.8 metres high, flanking an entrance about 80 centimetres wide. A massive roofstone, measuring 3.3 metres long and narrowing from 2.7 metres at the front to 1.7 metres at the back, now rests at an angle, supported by the broken portal stone and a prostrate slab.

The rectangular drystone structure built against the tomb’s western side served as a sheephouse in the mid-19th century, according to records from 1845-48 by Fagan, who noted the monument was already in its current ruined state by 1847. This later agricultural use, whilst damaging to the archaeological integrity of the site, ironically helped preserve what remains by incorporating the ancient stones into a functional structure. Today, even the sheephouse lies ruined almost to ground level, leaving both prehistoric monument and historic farm building as intertwined remnants of different chapters in this landscape’s long human story.
