The structure measures roughly 9 metres east to west and 10.4 metres north to south, its boundaries marked by a low earthen rim that has slumped and softened with time. The rim, ranging from 3 to 3.5 metres wide, rises only 10 to 20 centimetres on the inside but presents a more substantial 40 centimetre face to the outside world. A gap on the western side, about 2 metres wide, may have served as an entrance, whilst a large stone embedded in the southwestern corner adds to the enigmatic nature of the site.

The surrounding landscape tells its own story; the ground slopes away to wetter, lower terrain to the northwest, typical of this part of Donegal’s limestone country. A faint linear rise extends west-southwest from the structure, likely the ghost of an old field boundary that once divided these pastures. This barely visible feature hints at a landscape that has been worked and reworked over centuries, though the exact relationship between the boundary and the rectangular enclosure remains unclear.

What makes this site particularly intriguing is its mysterious nature; archaeologists haven’t been able to determine its precise function or date. It could be anything from a prehistoric settlement to a medieval animal enclosure, or something else entirely. The modest scale and simple construction suggest a practical, everyday purpose rather than anything ceremonial, but without excavation, its secrets remain buried beneath the Donegal grass. For now, it stands as one of countless unexplained features that dot the Irish countryside, a reminder that not every mark on the landscape comes with a neat historical label.
