It exists, officially and archaeologically, almost entirely as a ghost of itself, known mainly because a single aerial survey caught it at the right moment, in the right light, under the right crop conditions.

A ring-barrow is a circular earthen burial mound, typically of Bronze Age origin, defined by a surrounding ditch or bank that gives it its characteristic ringed outline when viewed from above. This particular example sits on a south-east-facing slope in improved pasture at Kilduff, about 80 metres north-east of the townland boundary with Pallas. It was first identified not by excavation or field survey but as a cropmark, the faint differential growth pattern that appears in grass or grain above buried features when soil moisture is uneven, during the Bruff aerial photographic survey of 1986. That survey recorded it as Bruff 158.3. The monument is one of a cluster of three ring-barrows in the immediate area, and lies close to a recorded enclosure and a feature called Keating's Well, just 25 metres to the north-east. An Ordnance Survey orthoimage taken between 2005 and 2012 still showed the faint circular trace, but subsequent imagery from Digital Globe and Google Earth, taken between 2011 and 2018, shows nothing at all. The record was compiled by Alison McQueen and Vera Rahilly and uploaded in October 2020.

There is no visitor infrastructure here, and the monument is not signposted. The site sits in working agricultural land, so access would require the landowner's permission. For anyone with an interest in aerial archaeology or the quieter end of the prehistoric record, the Bruff survey image is worth seeking out; it shows clearly what decades of pasture improvement and changing soil conditions have since obscured at ground level and from the air. The nearby Keating's Well may offer a more tangible point of reference on any visit to the area, as holy wells tend to retain a physical presence long after earthworks of this kind have faded.
