It exists, as far as the documentary record is concerned, only from the air, and even then only barely: a faint circular stain in the ground, roughly eight metres across, that reveals itself through the differential growth of grass above it.

The feature was first identified during a 1986 aerial photographic survey of the Bruff area, catalogued under reference AP 4/3615. That survey picked it out as a small circular earthwork, and subsequent aerial imagery confirmed what had been seen. A cropmark of the ring ditch is visible on Ordnance Survey Ireland orthophotos taken between 2005 and 2012, and again on Digital Globe imagery from 2011 to 2013. A ring ditch is, in simple terms, a circular or near-circular trench cut into the ground, often associated with prehistoric funerary or ceremonial monuments, though the term covers a range of features whose original purpose can be difficult to establish without excavation. That this one measures only around eight metres in diameter places it at the smaller end of the scale. The record was compiled by Martin Fitzpatrick and uploaded in April 2021.

Because the feature carries no surface expression, there is nothing to see at ground level. The wet, low-lying pasture that surrounds it makes access uninviting in most seasons, and without the benefit of aerial imagery taken at the right time of year, when soil moisture and grass growth conspire to make the cropmark legible, the site is effectively invisible. The best way to appreciate it is through the aerial photographs themselves, particularly the 1986 Bruff survey image. For anyone interested in the archaeology of the Bruff area more broadly, this site serves as a useful reminder of how much survives not in stone or earthwork, but as a faint signature written in the soil, only readable under particular conditions and largely absent from the maps that most people consult.
