This is a ditch barrow, a type of funerary monument in which a low mound is encircled by a surrounding fosse, or ditch, rather than built up from material heaped outward. The whole thing measures less than five metres across, and the ditch itself is only thirteen centimetres deep. The interior dome, rather than rising above the surrounding ground, sits level with it. Whatever once marked this as a place set apart from ordinary land has largely dissolved back into the earth.

Barrows of this kind are among the more enigmatic survivals of prehistoric Ireland. They are generally associated with Bronze Age burial practice, though the category covers a range of forms, and any more precise dating at Kilross would require excavation. The monument was formally identified during a field survey carried out by Alison McQueen and Vera Rahilly on 13 January 2009. At that point it had already been absorbed into improved agricultural land, the kind of levelled, fertilised pasture that does no favours to slight earthwork remains. What the surveyors recorded was the ghost of a structure: a roughly circular area, slightly longer on its north-south axis at 4.75 metres than on its east-west at 4 metres, with the shallow fosse around it measuring 2.2 metres wide. Nothing about it announces itself.
