A circular enclosure, roughly 26 metres across from east to west, was recorded on the first edition Ordnance Survey six-inch map of 1838, but by later editions the cartographers had redrawn it differently, marking the same spot with hachures suggesting a shallow hollow or quarry. Whether the earthwork had been largely levelled by then, or whether the surveyors simply misread what they were looking at, is not entirely clear. What remains is a feature that has slipped between categories, neither confidently identified as an ancient monument nor fully explained as a later extraction pit.

The 1838 OS six-inch maps, produced during the first systematic large-scale survey of Ireland, captured features that were already disappearing under the pressure of agricultural improvement. Circular enclosures of this general type are often associated with early medieval settlement, sometimes referred to as ringforts, which functioned as enclosed farmsteads. A diameter of 26 metres is modest but well within the typical range for such sites. The fact that later surveyors reinterpreted the feature as a hollow or quarry suggests the banks had lost much of their definition by the mid to late nineteenth century. Today, a cropmark of the enclosure remains partially visible from the south-east, south, and south-west on aerial photography, the kind of ghostly outline that appears when buried archaeology causes subtle differences in crop growth above it, making vegetation dry out or mature unevenly and betray the shape beneath.
