It sits on elevated ground, the kind of position that suggests deliberate choice, and its form has shifted, at least on paper, across the centuries. The Ordnance Survey mapped it as circular in 1837 and as broadly oval by 1913, which may reflect changes on the ground, differences in surveying precision, or simply the difficulty of capturing an earthwork that never quite conformed to a tidy shape.

What survives today is a subrectangular area, roughly 25.8 metres on its northeast-to-southwest axis and 21.8 metres across, enclosed by an earthen bank that varies considerably depending on where you measure it. At the southwest the bank reaches 4.4 metres wide, while at the northeast it narrows to 2.3 metres. The internal height, the rise from the enclosed interior up to the top of the bank, ranges from 0.8 metres at the northwest to 1.2 metres at the southwest, and the external face is lower still. Large boulders have been set into the inner face of the bank at the west and south, suggesting either structural reinforcement or the incorporation of earlier stonework. At the outer foot of the bank on the northeast side, a terrace about four metres wide and up to 0.8 metres high adds another layer of complexity to the earthwork's profile. Enclosures of this type, broad earthen banks defining a roughly circular or oval space, are found across Ireland and are associated variously with early medieval settlement, stock management, or ritual use, though without excavation it is rarely possible to assign a confident function to any individual example. The northwest section of the bank has been absorbed into a later field boundary at some point, the kind of practical reuse that was common as agricultural landscapes were reorganised across successive generations, and which gradually blurs the original geometry of a monument.
