What they left behind is a cashel, a type of ringfort defined by its stone construction rather than an earthen bank, and this one is unusually compact: a raised circular platform just nineteen metres across, ringed by a rubble limestone bank nearly eight metres wide but only about forty centimetres high on its interior face. No fosse, the defensive ditch that typically accompanies such enclosures, survives at ground level, which gives the site a quieter, less martial profile than you might expect.

The bank itself carries the evidence of later interference. Along its south-south-east to south-south-west arc, the outer face has been incorporated into a drystone field wall running east to west, a commonplace fate for prehistoric and early medieval stonework across rural Ireland, where dressed and undressed stone has always been a resource as much as a relic. Despite this reuse, the original entrance can still be read in the fabric of the site: a two-metre gap in the bank at the south-south-west, accompanied by a slight ramp, points to where people once passed in and out. More intriguing still is what lies just inside the north-east of the interior. A possible souterrain, an underground stone-lined passage or chamber typically associated with storage or refuge, sits roughly two metres from the internal base of the bank. Souterrains are a recurring feature of Irish ringforts and cashels, though whether this one was ever fully constructed, or has simply collapsed beyond easy recognition, remains an open question.
