Two editions of the Ordnance Survey map, including the revision published in 1922, mark a circular enclosure roughly forty metres in diameter, the kind of ring-shaped earthwork that in Ireland typically signals early medieval settlement or landholding. When surveyors visited the ground itself, they found nothing. No bank, no ditch, no trace of any kind.

The land where the enclosure was mapped had once been karstic scrubland, the sort of thin-soiled, limestone-fractured terrain common in Connacht, where hazel and thorny scrub colonise the gaps between exposed rock. At some point it was cleared, and whatever physical evidence had survived into the mapping era, if it ever existed as a genuine upstanding feature rather than a cropmark or a cartographer's interpolation, did not survive the clearance. Circular enclosures of this type, sometimes called ring forts or raths, were built across Ireland in their thousands during the early medieval period, serving as enclosed farmsteads with a raised earthen bank defining the boundary of a household's living space. Most leave some impression in the ground for centuries. This one, if it was ever there in any meaningful sense, left none.

What remains is a small puzzle about the relationship between maps and the land they describe. The Ordnance Survey's nineteenth-century fieldworkers were generally careful, but they recorded what informants told them as well as what they could see, and earlier features sometimes appeared on maps because local knowledge placed them there rather than because an earthwork was plainly visible. Whether this enclosure was a genuine monument that clearance erased entirely, a misread feature, or something passed along through local tradition and absorbed into the cartographic record, is now impossible to say.
