It measures approximately seven metres east to west and somewhere between five and seven metres north to south, with a bank of earth and stone defining three of its sides. That bank is not especially dramatic, rising less than a metre in internal height, but it is coherent enough to suggest that something deliberate was once built here, even if nobody can say with confidence what.

What makes this feature particularly curious is its documentary disappearance. The 1838 Ordnance Survey six-inch map records it clearly, showing a small circular feature at the meeting point of three field boundaries. Later map editions omit it entirely, which raises the question of whether surveyors simply chose not to mark it, or whether its already ambiguous outline had by then blurred too far into the surrounding landscape to warrant inclusion. The bank is now partly obscured by gorse and hawthorn, which does nothing to clarify its original form. A field wall runs along the northern side, effectively replacing the bank there, and another wall on a north-south axis abuts the southern edge. Archaeologists have cautiously described it as the possible remains of a small structure or hut, though that label carries more uncertainty than it might at first suggest.

What gives the site a slightly richer context is its proximity to two other monuments fifty metres to the north: a rath and an associated souterrain. A rath is a roughly circular earthen enclosure, typically dating from the early medieval period and most often interpreted as a farmstead; a souterrain is an underground stone-lined passage, usually found in association with such settlements and thought to have served for storage or refuge. Whether the Breaghwy hut site was connected in any way to that nearby complex is unknown, but the clustering of features on this low ridge suggests the area saw sustained, if now largely illegible, human activity.
