The mound beneath it climbs anywhere from 1.6 to 7 metres, its effective height boosted further by the natural slope of the ridge, so that the oval platform at the top commands clear sightlines in every direction. That combination of artificial construction and shrewd natural positioning is typical of the rath, a type of ringfort defined by an earthen bank rather than a stone wall, and usually associated with the farmstead of a relatively prosperous family during the early medieval period, roughly the fifth to twelfth centuries.

The platform itself measures roughly 29.7 metres east to west and 21.7 metres north to south, enclosed by the fragmentary remains of an earth and stone bank. Notably, there is no fosse, the encircling ditch that commonly accompanies such monuments, which gives the site an unusually clean silhouette. The original entrance survives on the eastern side, a gap about 2.6 metres wide with a ramp still visible, oriented towards the rising sun in a way that recurs at many Irish ringforts. Fragments of oyster shells turn up in the exposed soil on the outer face of the mound, a small but suggestive detail that hints at either domestic activity or the gradual accumulation of midden material over centuries of occupation. Inside the western part of the enclosure, a possible souterrain has been identified. A souterrain is an underground passage or chamber, typically stone-lined, and often interpreted as a place of storage or refuge connected to the surface dwelling above it. Whether this one is intact or partially collapsed is not recorded, but its presence adds another layer to what is already a well-preserved example of a coastal settlement site.
