It is a rath, the Irish term for a ringfort, one of the most common monument types in the Irish landscape. Typically dating from the early medieval period, raths were enclosed farmsteads, their circular banks and ditches defining a domestic space rather than a military one. This particular example is somewhat larger than average, measuring about 53 metres across one axis and nearly 66 metres across the other, and what makes it quietly absorbing is the layered evidence of everything that has happened to it since it was first built.

The enclosure is defined by an earthen inner bank, which at its best-preserved section on the western side still stands nearly two metres high externally and carries a noticeably flattened top. The bank incorporates stones and occasional boulders alongside the earth, and on the north-eastern arc it has been absorbed into a field fence, which follows the curve of the old enclosure so faithfully that the two are now inseparable. That repurposing has given the bank a sharper, almost triangular cross-section in that stretch. Outside the inner bank, a fosse, or ditch, runs from the south-west around to the north, accompanied by a lower external bank whose line diverges at the northern end to join a later field boundary. Whether this outer bank is original or was added at some point after the rath was built is unclear, but the divergence suggests modification at some stage in the more recent past. The original entrance cannot be identified with certainty; there are several breaks in the bank, the widest of them on the east-south-eastern side at just over ten metres, but none can be confirmed as the first way in. The north-western quadrant has suffered more decisively: a large quarry pit, roughly 24 metres by 15 metres and up to about 1.4 metres deep, has removed a substantial portion of that section entirely. And in the south-western quadrant, recorded on the Ordnance Survey six-inch map of 1915 simply as "Grave", there is a burial, a quiet detail that adds an additional layer to a site already carrying centuries of accumulated use and alteration.
