A rath, as these earthen enclosures are known, was typically a circular farmstead of the early medieval period, its bank and ditch serving as much for status and livestock management as for any serious defence. This one sits on a gentle east-facing slope among the sand banks behind Fionntrá, and its absence from the historical maps makes it an easy thing to overlook, which is perhaps why it has survived at all.

The enclosure measures roughly 25 metres north to south and 22 metres east to west internally, with an earthen inner bank that rises to about 1.5 metres on its outer face, though considerably less on the interior. Beyond that runs a fosse, a defensive ditch, approximately 8 metres wide, and beyond that again a second outer bank, though both features are present only along the northern half of the site. Whether this partial survival reflects original construction choices or later erosion is not certain. Three breaks interrupt the inner bank, and surveyors working from J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne region identified the 2.4-metre gap at the northwest as the most likely candidate for the original entrance. The rabbit population has been busy here over the years, with burrows disturbing considerable portions of the site, adding a layer of small-scale geological disruption on top of centuries of coastal weathering and sand movement.

The fort sits within a wider landscape on the Dingle Peninsula that is extraordinarily dense with early medieval and prehistoric remains, but this particular site rewards those who seek it out precisely because it has none of the signposting or management that comes with better-known monuments. The sand bank setting gives it a slightly surreal quality, a domestic enclosure of the early Irish countryside now embedded in coastal dunes, its northern earthworks still just legible against the sky.
