These are kerb stones, the kind that would once have formed the outer retaining edge of a prehistoric cairn, a mounded burial structure typically built from heaped stone. What makes the site quietly puzzling is how little of that mound survives. The interior has been largely stripped, almost certainly robbed of its stone at some point in the past, leaving the kerb-like perimeter to define a space that is now mostly empty.

The stones themselves are substantial, ranging up to almost two metres in length and over a metre in height, and they delimit an area of roughly 8.5 metres north to south by 9.3 metres east to west. They sit in a continuous series around the perimeter, though several are missing along the southern side and others have fallen along the western edge. A little cairn material does survive on the exterior along the northern side, suggesting something of the original structure can still be read in the landscape if you know what to look for. The site was noted by Cremen in 1929 and has been compared with similar monuments in the region, including cairns at Cuppage and Knockaunavadreen, as well as a multiple cist cairn at Moneen. A cist, for context, is a small stone-lined burial box, and cairns of this type were frequently raised over one or more such burials during the Bronze Age. Whether the stripped interior here ever contained cists is now difficult to say.
