A circular enclosure some 32.5 metres in diameter, it survives now only as fragments: a low earthen bank visible at the northern side and from the south-east around to the south, and a scarp, a slight step or break in the ground surface, defining its southern and south-western arc. Everywhere else, the surface has given nothing back.

Enclosures of this kind are broadly prehistoric or early medieval in origin, though without excavation it is rarely possible to say which. They are distinct from ringforts, the more familiar circular earthworks that served as defended farmsteads across early medieval Ireland, though the two types are easily confused and often found in proximity. Here, a ringfort lies roughly 100 metres to the north-north-east, suggesting this stretch of Slievedarragh once held a small cluster of activity, whatever its precise nature. The enclosure itself may have functioned as a stock pound, a burial ground, or something more ceremonial; the archaeology does not say, and the surviving remains are too fragmentary to press the question further.
