What survives at Balrobuck More is a circular enclosure roughly forty metres across, its perimeter now only a low, grass-covered bank of earth and stone. That bank traces an arc from the south-west around through the north to the north-east, and then stops, because a later field wall cuts across the monument at both those points, and to the south-east of that wall no surface trace of the original structure remains at all.

Enclosures of this kind, defined by a raised earthen bank sometimes reinforced with stone, are among the most common archaeological features in the Irish landscape, though their dates and functions vary considerably. Some enclosed farmsteads, some served a ritual purpose, and many remain difficult to classify without excavation. At Balrobuck More the monument is described as being in poor condition, which is itself a kind of history: centuries of agriculture, the insertion of field boundaries, and the general persistence of working land have worn it down to this partial arc, legible if you know to look, easy to miss if you do not.
