It is compact, almost domestic in scale, measuring roughly 4.7 metres by 4.5 metres internally, with a bank no more than half a metre high and less than a metre wide. Enclosures of this kind are a recurring feature of the Irish countryside, and their purposes varied considerably, from livestock management to the delineation of a dwelling space or even a ritual boundary, but their precise function is rarely easy to establish from the physical remains alone.

What makes this one quietly compelling is precisely its modesty. The D-shape is a recognised form in early Irish archaeology, often associated with small farmsteads or ancillary structures attached to larger ringfort complexes, though the available evidence here does not allow a firm identification. A. O'Sullivan and J. Sheehan documented it as part of their archaeological survey of the Iveragh Peninsula, published by Cork University Press in 1996, a project that brought systematic attention to a region whose archaeological record had long been underappreciated relative to its density of sites.
