The Ordnance Survey mapped it as a rath in 1842, a form of enclosed settlement typical of early medieval Ireland, then relabelled it a carn on later editions, and the state record classified it as a cairn as recently as 1996. What it actually appears to be is something older and simpler: a hut site, the remains of a structure whose occupants would have looked out across the same wide views that the ridge commands today.

The site is subcircular in plan, with an interior diameter of roughly eight metres and overall external dimensions of fifteen metres north to south and twelve metres east to west. It is defined by a bank of earth and stone, between two and five metres wide, that still stands up to 1.2 metres high on its outer face. At the northeast, two stone slabs set on edge form what appears to be an inner revetment, a low facing wall used to retain and stabilise the bank material. A modern field wall running just outside the western edge of the bank may itself have been built partly from an earlier outer revetment, cannibalising whatever structural stone was once there. Loose stones lie scattered across the interior, suggesting that any original surface features have long since been disturbed by farming or stone clearance. About forty metres to the southwest lies a separate megalithic structure, lending the immediate area a quiet density of prehistoric activity that the unassuming ridge-top landscape does little to advertise.
