It is a ring-ditch, a term used to describe a circular ditched enclosure, often the remains of a prehistoric burial monument or a ritual site, where the original earthwork has been ploughed flat over centuries, leaving only a ghostly outline detectable as a cropmark. Cropmarks appear when buried features, such as the fill of an old ditch, affect the growth of crops above them, producing a faint but readable pattern when viewed from altitude, particularly during dry summers when the contrast is most pronounced.

This particular feature was identified and reported by Jean-Charles Caillère, who spotted it on satellite imagery captured in August 2015. What gives the site additional interest is its relationship to a neighbour: a concentric enclosure, a separate monument comprising rings set one within another, lies roughly fifty metres to the north-west. The proximity of these two features in the same field suggests this small corner of Kilkenny may have held some significance in the prehistoric landscape, though the plough has long since erased any surface trace of what that significance looked like.
