Its drystone wall, roughly built and broadly indistinguishable in construction from the ordinary field walls around it, has been folded into the surrounding field boundary system so completely that a casual eye might pass over it without pause. What marks it out is a narrow gap, just one metre wide, in the wall at the north-east; the kind of detail that suggests purpose rather than accident.

When the Ordnance Survey was mapping Ireland at six inches to the mile in 1837, this enclosure was recorded as a roughly circular feature sitting in isolation, unattached to any adjoining field system. That is a meaningful distinction. Sometime between that first survey and the present, the enclosure was absorbed into the working agricultural landscape, its wall re-used or extended to serve as an ordinary field boundary. The structure itself measures approximately 26.3 metres east to west and 21.5 metres north to south. Enclosures of this general character, found across Ireland, are often associated with early medieval settlement or farming activity, though without excavation it is rarely possible to say with certainty what any individual example was built for or when.
