It is roughly subcircular, measuring approximately 49 metres north to south and 46 metres east to west, and its edges are defined by a low scarp, a kind of earthen step or revetment, rising between 0.8 and 1 metre. What makes it quietly unusual is that this scarp has been faced with drystone masonry, meaning someone at some point took the trouble to line its interior edge with carefully laid unmortared stone, giving the enclosure a more finished character than a simple earthwork would suggest.

By the time the Ordnance Survey produced its six-inch map series in 1837, the site was already being labelled simply as "Fort", the shorthand commonly applied to ringforts, which are enclosed farmsteads or settlement sites typical of early medieval Ireland, usually surrounded by one or more earthen banks and ditches. This one, however, shows no trace of a fosse, the surrounding ditch that normally accompanies such a bank, and its original entrance has been lost entirely. A section running from the west-north-west around to the north-north-west has been cleared away altogether, replaced by a hedgerow and field fence running north-east to south-west. Elsewhere, modern field boundaries press up against the base of the surviving scarp rather than cutting through it, which has at least helped preserve what remains. Whether the drystone facing was an original feature or a later practical addition, perhaps to firm up a deteriorating earthen edge, is not clear from what survives.
