It is a rath, the Irish term for a ringfort, which was the standard form of enclosed farmstead used across early medieval Ireland, typically between the sixth and tenth centuries. What makes this particular example quietly interesting is not grandeur but geometry: a near-circular platform measuring roughly 36.6 metres north to south and 34 metres east to west, defined by an earthen bank that still stands 1.55 metres high on its outer face, accompanied by a fosse, that is, a surrounding ditch, dropping around 0.75 metres deep.

The entrance is readable even now. A gap in the bank to the north is paired with a causeway crossing the fosse, the classic arrangement that gave a rath its single controlled point of access. The interior slopes gently northward, and both the bank and the inner ground have been planted with larch and pine, which gives the enclosure a slightly different character from the surrounding pasture. A concentric field fence running from the south-east round to the north hints at a possible outer bank, though the low scarp continuing from north back to south-east is ambiguous enough that it could equally be the remnant of old ploughing rather than a deliberate second line of defence. To the east, there is a possible souterrain associated with the site, an underground passage or chamber of the kind often found in connection with ringforts, used variously for storage, refuge, or the keeping of dairy produce in a cool environment. Whether this one is intact or accessible is not clear from what survives on record.
