The structure is small, roughly twenty metres across from east to west and sixteen metres north to south, defined by a modest bank of earth and stone. In places that bank has been reduced to little more than a scarp, a slight step down from the raised interior to the surrounding ground. It is easy to overlook, and that is part of what makes it interesting.

The antiquarian Thomas Johnson Westropp, writing in 1905, described what may be this same feature as a fort, square in plan and roughly sixty feet each way, built of large but late-looking masonry, and probably an old cattle-bawn. A bawn was an enclosed yard, typically attached to a tower house or fortified dwelling, used to pen livestock and offer a degree of security; the term is common across Irish late medieval and early modern archaeology. Whether Westropp's square fort and the subcircular platform recorded here are the same structure, or whether the stonework he observed has since disappeared, is not entirely clear. What is certain is that the enclosure sits within a relict field system, the remains of older agricultural boundaries that can still be traced across the landscape, and within a larger multiperiod field system that speaks to centuries of farming activity in the area. A second enclosure lies roughly fifty metres to the north-east, suggesting this was never an isolated feature but part of a wider pattern of land use and enclosure across the townland.
