It is easy to walk past, easy to dismiss as a trick of the ground, and that is part of what makes it worth pausing over.

The feature is D-shaped in plan, measuring roughly 8.8 metres along its northwest to southeast axis and projecting about 6 metres to the northeast. It is enclosed by a low bank of earth and stone, the interior face of which rises only around 0.4 metres, while the exterior face is barely 0.15 metres above the surrounding ground. Along the top of a scarp running southeast to northwest, a few stones remain visible at the surface. There is a gap of about 1.3 metres in the scarp to the southwest, possibly an original entrance or a later break. The interior is described as saucer-shaped, meaning it dips gently inward rather than sitting flat, a characteristic seen in certain enclosed earthworks across Ireland where the ground within the bank has settled or was deliberately formed that way. What function this particular enclosure served is not recorded. Its modest scale and construction suggest something other than a major defensive or ceremonial purpose, though such earthworks can represent anything from a small agricultural enclosure to the remains of a structure whose upper elements have long since disappeared into the soil.
