The structure is small, roughly eight and a half metres north to south and five metres east to west, and its roughly rectangular outline would be easy to walk past without registering what it once was. An enclosure of this kind, defined by a drystone boundary wall rather than an earthen bank, is a common enough form across Ireland, used historically for everything from small-scale agriculture to the penning of animals, though the precise original function here is unknown.

What the bog has done to it is the quietly interesting part. Blanket bog, which accumulates slowly over centuries as waterlogged vegetation fails to decompose, has a tendency to preserve and then partially conceal the things it grows across. Here, the wall survives to a height of about half a metre and a thickness of around eighty centimetres, and it is best preserved along its eastern side. A possible entrance opening survives in the north-east corner. The interior of the enclosure slopes downward toward the south, following the natural gradient of the hill. Beyond that, the site does not give much away.
