A cashel is a type of early medieval ringfort defined by a drystone enclosure wall rather than an earthen bank, and this one, measuring roughly 27.6 metres across its northeast to southwest axis, survives in reasonably good condition. The complication is that what looks well-preserved has been quietly altered. The monument was embellished during the nineteenth century through field clearance and a programme of so-called restoration, and the traces of that intervention are legible once you know where to look.

The most conspicuous modern additions are a gap at the northeast and a corresponding external staircase, apparently built to allow access up onto the wall head. The gap at the west seems equally modern, though here someone later blocked the opening with mortared stonework and tucked a doorway into it, which has itself since been blocked up. This layering of interventions, early medieval construction, nineteenth-century tidying and embellishment, and subsequent blocking, gives the monument a complicated biography. Further complicating any reading of the interior, two ruined field walls cut across it, running roughly from north-northeast to west-northwest and from south-southeast to south respectively, suggesting the enclosure was at some point incorporated into the ordinary working geometry of the surrounding farmland rather than preserved apart from it.
