What was once an oval earthwork, roughly 30 metres along its longer axis and 24 metres across, is now so thoroughly levelled that only a very slightly raised circular area of about 13.5 metres in diameter remains visible on top of the rise. The difference in height between this trace and the surrounding ground is subtle enough that most walkers would pass over it without a second glance.

What makes this site particularly curious is the gap in the cartographic record. When the Ordnance Survey produced its six-inch maps in 1837, the enclosure was not recorded at all, yet by the 1913 edition it appears clearly, rendered in the hachured style that surveyors used to indicate an earthen enclosure, with a large break noted at the north-east. Hachuring on OS maps of this kind typically signals an upstanding earthwork, the kind of roughly circular or oval banked boundary found across Ireland in various forms, from prehistoric ring-barrows to early medieval enclosures associated with settlement or ritual use. Whether the monument was simply missed in 1837, or whether it was more visible by 1913 due to changes in land use and vegetation, is impossible to say with certainty. What is clear is that at some point after 1913 it was levelled, leaving only the natural topography beneath as any indication that something once stood here.
