The raised area measures roughly 33.8 metres east to west and 27 metres north to south, its perimeter defined by a bank of earth and stone that is no more than 30 centimetres high and about 4 metres wide. That modest ridge is all that remains of a rath, the Irish term for a ringfort, a type of enclosed farmstead typically dating from the early medieval period, roughly 500 to 1000 AD, when such enclosures were the standard unit of rural settlement across the island.

What makes this particular example quietly interesting is how thoroughly the landscape has absorbed it. The enclosing bank has been incorporated into a field boundary running northeast to southwest, so that the ancient structure and the working division of agricultural land have become, in places, indistinguishable from one another. There is no fosse, meaning no surrounding ditch of the kind that typically accompanied earthen ringforts and gave them a more pronounced defensive or demarcating profile. Whether the fosse was never dug, or was simply levelled away over centuries of farming, is not clear. The original entrance has also been lost, leaving no obvious break in the bank to indicate how its inhabitants once came and went. The site sits on a rise bordering a tidal inlet, a position that would have offered both drainage and a degree of visibility across the bay.
