The structure has never appeared on any edition of the Ordnance Survey six-inch maps, making it cartographically invisible for the entire period those maps have existed. It came to light only through aerial photography, which is itself a reminder of how much the Irish landscape still holds that ground-level survey work has not yet reached.

The enclosure is formed by a sod-covered, gravelly bank incorporating occasional large stones, modest in scale but clearly deliberate: roughly 2.3 metres wide at its base, with an interior height of around 0.2 metres and an exterior height of about 0.55 metres on the north-western side. A shallow depression, or fosse, runs along the inner edge of the bank on that same north-western arc. There is a broad opening in the north-east, roughly 7.4 metres wide, and several smaller breaks or eroded sections along the southern and south-western sides. What purpose this enclosure served remains genuinely uncertain. It does not appear to be a rath, the circular or oval earthwork typically associated with early medieval farmsteads in Ireland. One possibility is that it is a relatively late cultivation plot, making deliberate use of the higher, drier ground the natural rise provided, since before modern drainage was introduced the surrounding terrain would have been wet and largely unusable. Against this reading, there are no visible cultivation ridges inside. The interior slopes down from the centre towards the south-east, the surface is uneven and tussocky, and a concentration of loose stones sits near the southern end. Several small quarry pits, each roughly eight to ten metres across, cut into the slope beyond the enclosure to the south-east.

The site sits with clear views in all directions, about 500 metres south of the Robe River, on ground that rises to around two metres above the surrounding pasture at its south-western end. It is the kind of place that rewards patience with the landscape rather than any obvious legibility: a boundary of uncertain age and purpose, pressing quietly against a hillside that has been worked, drained, and grazed into a state where the original logic of the thing may no longer be recoverable.
