What makes it worth a second glance is what lies at its centre: a polygonal cist, a small stone-lined burial chamber of prehistoric origin, still partly visible despite centuries of neglect and what appears to be deliberate interference.

The cairn itself is a substantial structure, measuring roughly 16 metres east to west and just over 15 metres north to south, and rising between one and two metres at its highest point. At its heart, four stones arranged in a polygonal formation mark the cist, though they are no longer contiguous, meaning the original tight arrangement of slabs has been broken. The likely cause is visible nearby: a depression at the south-west edge of the cairn, about two metres long and less than a metre wide, suggests stone was quarried from the mound at some point, disturbing the burial chamber in the process. The cist stones are now thickly overgrown with moss. The monument was formally recorded in the Record of Monuments and Places in 1996, listed in the plural as "cairns", though the surviving evidence points to a single main structure. The wide basin opening to the south-east below the site, with slightly higher ground rising to the west, gives the location a quietly considered quality, the kind of placement that recurs in prehistoric burial landscapes across Ireland, where the relationship between a monument and its surrounding terrain often seems anything but accidental.
