A rath is an early medieval ringfort, typically a defended farmstead enclosed by one or more earthen banks, and this example follows the familiar form: a circular interior roughly 35 metres across from south-east to north-west, bounded by an earthen bank, a fosse (a drainage and defensive ditch), and an outer bank beyond that. What makes it quietly arresting is how much of that layered boundary has been worn away. The inner bank has been reduced almost entirely to a low scarp, and the fosse and outer bank survive only on the western and southern sides, giving the impression of a structure that has been slowly absorbed back into the hillside.

The outer bank, where it does remain, reaches an external height of around 0.7 metres, its base between one and a half and two and a half metres wide, and the fosse beside it just under two metres across. There are two gaps in what remains of the inner bank: a modern breach about three metres wide on the western side, probably made for agricultural access at some point in recent centuries, and a wider gap of four and a half metres at the south-west that may represent the original entrance to the enclosure. That entrance position, facing south-west, is fairly common in Irish ringforts, thought by some researchers to reflect a preference for morning light in the interior. At the centre of the enclosure, a small quarry has been dug at some point, cutting into the very ground the rath was built to enclose.
