But the shape beneath those trees is deliberate and ancient: a near-perfect circular enclosure roughly 28 metres across, its perimeter defined by an earthen bank that still stands up to two metres high on its outer face. What makes it quietly puzzling is what is absent. There is no fosse, the external ditch that typically accompanies an earthen bank and from which the material to build it would have been dug. And no entrance can be identified anywhere around its circuit.

Enclosures of this type are broadly understood as ringforts, the most common monument type in the Irish landscape, built and occupied roughly between the early medieval period and the Norman arrival. They served as enclosed farmsteads, the bank and any accompanying ditch providing a degree of security for a household and its livestock. The absence of a fosse here is unusual; in most examples the ditch is the defining feature, its spoil thrown inward to form the bank. Whether the fosse was never dug, has silted and flattened entirely over the centuries, or was simply not required for the particular character of this site remains an open question. The enclosure sits on a north-east-facing slope with a stream running roughly west to east some ninety to a hundred metres to the north, a placement that is consistent with early agricultural settlement, where reliable water nearby was a practical necessity rather than an accident of geography.

The bank itself is five to six metres wide at its base and retains a modest but measurable internal height of around half a metre to a metre, suggesting it has survived reasonably intact despite the planting that now obscures it. The conifers, introduced at some unknown point, have done the monument the ambiguous service of both sheltering it from agricultural disturbance and making its form harder to read from the ground.
