It measures about 7.5 metres by 5 metres and rises only a metre above the surrounding bog, modest enough that a casual walker might dismiss it as a natural feature of the landscape. It is not. This is a prehistoric cairn, a deliberate accumulation of stone that once marked something significant, though exactly what, whether burial, ritual, or territorial, the bog has been keeping its own counsel for millennia.

What makes the site particularly interesting is that the cairn does not stand alone. Within a short distance, two other prehistoric monuments occupy the same hillside: a five-stone circle lies roughly 11 metres to the north-north-west, and a stone row sits about 7 metres to the north-west. Five-stone circles are a type of small stone circle found almost exclusively in Cork and Kerry, typically consisting of four upright stones with a fifth, recumbent stone placed between two portal stones. Stone rows, as the name suggests, are alignments of standing stones, often interpreted as having had astronomical or ceremonial significance. That three such monuments cluster together here on the southern extension of Burraboy Mountain suggests this was a deliberately chosen, purposefully arranged landscape, possibly used over an extended period during prehistory. The site was catalogued by Seán Ó Nualláin, whose surveys of Cork and Kerry stone circles and related monuments in the 1980s remain foundational references for this type of complex in the region.
