Known on older maps as Greyfort, it measures roughly twenty to twenty-two metres across, its enclosing wall now barely visible beneath decades of overgrowth. What makes it quietly puzzling is a question that remains unresolved: nobody is entirely certain whether that wall is an original early medieval feature or something constructed in the modern era. The structure underneath the vegetation could be genuinely ancient, or it could be a much later imitation of one.

Ringforts are circular enclosed settlements, typically of early medieval date, once used as farmsteads by individual families across Ireland. They appear in their thousands across the country, though their condition varies enormously. This particular example first appears cartographically on the 1838 Ordnance Survey six-inch map, where it is recorded as a circular embanked enclosure. By the 1922 edition it had acquired both a stone wall and the name Greyfort. The wall itself is modest in scale, around 1.3 metres wide and standing less than a metre in external height, and is now largely engulfed in vegetation. More intriguing than the wall, however, is what lies at the centre of the interior: a souterrain, an underground stone-lined passage or chamber of the kind frequently associated with early medieval settlement sites, where they may have served for storage or concealment. Its presence here at least suggests that something genuinely old underlies the enclosure, whatever the ultimate date of the wall above ground.
