This modest megalithic monument sits roughly 900 metres south-southwest of a better-known court tomb in the same townland of Tawlaght. From this sloping ground, visitors can take in sweeping views to the north and south, whilst Crockkinnagoe Hill looms impressively at 364 metres to the east. A series of low hills blocks the western horizon, creating a natural amphitheatre around this prehistoric site.

The tomb itself consists of a partially roofed stone gallery measuring just 2.3 metres in length, oriented unusually from south-southwest to north-northeast rather than following the typical east-west alignment common to such monuments. The gallery narrows from 0.95 metres at its southern end to 0.75 metres at the north, with each side formed by two upright stones, or orthostats, standing between 0.4 and 0.45 metres high. A substantial roofstone, measuring 1.8 by 1.7 metres and up to 0.4 metres thick, still rests atop these sidestones. About a metre beyond the gallery's southern end, what appears to be a facade stone stands perpendicular to the western side, though it now leans southward. The entire structure sits within a low, grass-covered oval mound measuring 8.5 by 6.4 metres, barely rising 0.3 metres above the surrounding bog.

The area around the tomb reveals further traces of ancient activity. Approximately 12 metres to the east, a rectangular heap of stones stretches for about 10 metres, rising half a metre from the boggy surface with low upright stones forming a facing around much of its perimeter. Five metres further east, a gapped line of set stones appears to be the remnants of an ancient field wall, suggesting this remote spot was once part of a more extensive prehistoric landscape. First noted in archaeological literature in 1951 and later surveyed by Eamon Cody for the comprehensive Survey of the Megalithic Tombs of Ireland, this unassuming monument offers a glimpse into Donegal's Neolithic past, quietly enduring in its bogland setting for perhaps 4,000 years.
