Roughly fifty metres across, it survives not as a visible earthwork but as a cropmark, the kind of ghost impression left in cereal crops when buried features alter how the soil retains moisture and nutrients. A narrow fosse, which is essentially a ditch dug to define or defend a space, traces the arc of the circle from the south-west, around the west, and up to the north-east. Then a road cuts across it, and on the south-eastern side, the mark simply disappears.

What makes this particular enclosure quietly puzzling is the uncertainty about what it actually was. Circular enclosures in Ireland are often assumed to be raths or ringforts, the enclosed farmsteads that dot the countryside in their thousands from the early medieval period. But the narrow profile of the fosse here prompted the suggestion that it may instead have been ornamental in purpose, a landscaped feature rather than a defensive or agricultural one. When a gas pipeline was laid beneath the road through the relevant area in 2015, archaeological monitoring uncovered no material that could be connected to the enclosure, leaving the question of its origin and date unresolved. The road that bisects the site appears to have truncated it at some point, removing whatever trace may have existed on the south-eastern side entirely.
