It measures just 5.5 metres east to west and 4.6 metres north to south, its interior oddly level and tending towards square rather than the rounded shape its outer bank suggests. That bank, faced on the inside with rounded stones and boulders and partly faced on the outside along its western arc, still stands to an external height of 0.7 metres in places. A low, eroded gap about 1.2 metres wide at the north-north-west may once have served as an entrance. Whether this was a house, a hut, or something else entirely, nobody has yet been able to say with confidence.

What makes it particularly elusive is its absence from the Ordnance Survey's first detailed mapping of the area. The six-inch map produced in 1838 shows no trace of it; only by 1922 had it been recorded, appearing as a small circular hachured feature, the cartographic convention of the time for showing a mounded or raised outline on the ground. That gap of nearly a century tells its own quiet story. The site sits on a gentle slope that falls away southward towards a stream, and roughly 260 metres to the north-east lies a rath, the type of circular earthen enclosure most commonly associated with early medieval farming settlements in Ireland. Whether there is any connection between the two features, in date or in function, remains an open question.
