What makes it quietly anomalous is the way it was formed: not by a single constructed boundary, but by a combination of a natural riverbank curving along its eastern edge and a deliberate linear scarp, essentially a man-made earthen step or cut edge, running along the southwest and southeast. The result is a roughly triangular space, approximately eleven metres north to south and eight and a half metres across at its widest, that uses the landscape itself as part of its definition.

Enclosures of this kind are a recurring feature of the Irish archaeological record, and their purposes varied considerably. Some were domestic, defining a protected area around a dwelling. Others were agricultural, ecclesiastical, or associated with activities that left little trace. Here, the scarp reaches about a metre in height, enough to mark a deliberate boundary without forming anything as substantial as a bank or wall. The interior slopes gently downward toward the north, toward the river, and the whole thing sits within a wooded area where the combination of tree cover, undergrowth, and the natural noise of moving water would have made for a reasonably sheltered, self-contained space. Without excavation, any more specific interpretation would be speculation.
