No raised ground, no stones, no obvious trace of anything at all. The monuments exist, in any meaningful sense, only as marks on a photograph taken from the air in 1986.

A ring-barrow is a circular burial mound, typically of prehistoric origin, defined by a surrounding ditch or bank. The example at Kilduff, along with up to five others nearby and a central enclosure, sits in wet, level pasture roughly 45 metres northwest of the townland boundary with Ballyhurst, with open sightlines towards Knockseefin to the west-northwest. The cluster does not appear on any Ordnance Survey Ireland historic maps, which suggests it was either too slight to record or had already been reduced to near-invisibility by the time systematic mapping was underway. What brought it to attention was an aerial photographic survey carried out from Bruff in 1986, catalogued as Bruff 90.06 and AP 4/3678. Aerial photography of this kind works by picking up cropmarks or soilmarks, subtle differences in how vegetation grows or soil drains that betray the presence of buried features below the surface. By the time an OSi orthophoto was taken sometime between 2005 and 2012, those surface signals had gone, and a Google Earth image from November 2018 confirmed there was still nothing visible at ground level. The record was compiled by Martin Fitzpatrick and uploaded in April 2021.

For a visitor, the honest truth is that there is little to observe in person. The site sits in private farmland, and the wet, level ground offers no dramatic contours to follow. What makes the detour worthwhile, if anything does, is the quiet conceptual puzzle of it: a possible prehistoric burial complex that revealed itself once, briefly, from the air, and has since returned to complete invisibility. The views towards Knockseefin remain, and the townland boundary with Ballyhurst runs close by, two of the few fixed points by which the site can be located at all.
