A circular enclosure clearly marked on the 1842 Ordnance Survey map had vanished entirely from the later edition, leaving no obvious trace on the landscape. What remains today is a small, irregular mound, measuring roughly 26 metres by 16 metres and rising no more than 0.8 metres above the surrounding ground, modest enough to be overlooked without a second thought.

That low rise in the earth may hint at something considerably older underground. Archaeologists have suggested the mound could represent the collapsed remains of a souterrain, a type of underground stone-lined passage or chamber built during the early medieval period, typically associated with nearby settlement sites such as raths or ringforts. Souterrains were used for storage, refuge, or both, and often survive only as subtle depressions or mounds once the enclosures they served have been levelled by centuries of agriculture or erosion. The circular enclosure itself, visible to the surveyors who produced the 1842 map but gone by a later revision, points to a settlement feature that was already fading from the surface within a relatively short span of recorded time.
