Measuring roughly 60 metres by 40 metres, it is the kind of feature that rewards careful looking; from a distance, or in flat light, the banks barely register, but in low winter or evening sun the earthworks cast just enough shadow to reveal the outline of something deliberately made.

The enclosure appears on the 1838 Ordnance Survey six-inch map, which places it firmly in the record by the early nineteenth century at the latest, though whether it originated then or earlier remains uncertain. In the north corner, a rectangular house platform survives with internal dimensions of approximately 7 metres by 3 metres, roughly the footprint of a single modest dwelling, and there may be a second platform immediately to its north. The classification carries a cautious qualifier: the site is described as possibly modern, meaning it could be a relatively recent agricultural or settlement feature rather than a relic of earlier centuries. That ambiguity is itself part of the interest. Ireland's upland commons are scattered with enclosures and platforms whose origins blur between post-medieval farming practice, pre-Famine smallholdings, and much older land use, and Ballyremon offers no easy answer.
