It exists, as far as can be determined, only in an aerial photograph, a single frame from an Air Corps survey that caught the outline of something half-buried in brambles, ferns, gorse, and deadwood on the western edge of a steep mountain stream gorge.

The photograph revealed what appears to be a D-shaped enclosure, a form common in early medieval Ireland, where a roughly circular or oval area was defined by a bank and ditch and used variously as a farmstead, a place of ritual, or a defended residence. Here, the gorge itself may have served as the eastern boundary, the natural drop of the land doing the work that a constructed earthwork would otherwise provide. Whether the enclosure was built to take advantage of that edge, or whether the gorge and the structure simply happen to share a border, cannot be said. The undergrowth has seen to it that no ground-level inspection has confirmed what the aerial view suggested.
