The enclosure is defined not by a wall or ditch but by a scarp, a sloping bank of earth, furze-covered and up to 1.8 metres high in places, that traces a rough oval roughly 46 metres across one axis and 53 metres across the other. A narrow entrance gap, just 1.5 metres wide, opens to the west-southwest. There is no obvious fosse, the external ditch that typically accompanies defended enclosures, which makes its precise purpose and date harder to read. An Ordnance Survey triangulation pillar now sits off-centre inside the south-western half, a twentieth-century addition that, in its own way, confirms what the enclosure's builders already knew: this hilltop sees in every direction.

The site appears on all editions of the Ordnance Survey's historic mapping, which places its recognised presence in the landscape at least as far back as the nineteenth century. Writing in 1908 to 1909, the antiquary T. J. Westropp noted that the interior, or garth, an older term for an enclosed yard or garden, had been tilled, and that the fort had by then been divided between two farms. That agricultural incursion explains some of what survives today: the north-eastern interior is rounded and falls steeply to the scarp edge, thick with briars and ferns, while the south-western half is level and relatively clear. The 1921 edition of the Ordnance Survey six-inch map recorded the topography in enough detail that its hachure markings still help interpret the earthwork's profile. The site does not stand alone in its ambitions for high ground. Several ringforts, the circular enclosed farmsteads of early medieval Ireland, occupy similarly conspicuous hillocks nearby, suggesting that this stretch of Clare landscape was once well settled and carefully organised across its elevated ridges.
