What makes it quietly anomalous is its shape: most early Irish enclosures of this kind tend toward the circular or oval, the form associated with ringforts and early medieval settlement. A rectangular plan is comparatively unusual, and that alone makes this modest feature worth a second look.

The enclosure measures 8.5 metres north to south and 4.4 metres east to west, defined by a low bank of earth and stone now softened under grass, roughly half a metre high and less than a metre wide. At the north-east corner, a large boulder has been incorporated directly into the bank, suggesting the builders worked around what was already on the ground rather than clearing the slope entirely. A narrow entrance, just 0.5 metres wide, sits at the centre of the western side, and the interior itself drops steeply away toward the south, following the natural gradient of the hillside. The function of the enclosure is not recorded; it could relate to agriculture, to the management of livestock, or to something older altogether, and its position overlooking the Clydagh valley offers no immediate answer.
