This is a cashel, a type of ringfort defined by a stone wall rather than an earthen bank and ditch, and this particular example retains much of its original fabric. The wall measures around three metres thick and stands to approximately 1.3 to 1.4 metres in height on both its internal and external faces, which is a reasonable survival for a structure likely dating to somewhere between the sixth and tenth centuries. What complicates the picture slightly is that the internal face has been reinforced at some point with a later drystone addition, 0.55 metres thick, some of which sits directly on the base of the earlier cashel wall. The two phases of construction are now difficult to disentangle without closer investigation.

The enclosure is roughly 36 metres east to west and about 35 metres north to south, making it a fairly substantial example of its type. A gap of around two metres on the east-north-east side may represent the original entrance, though certainty is elusive where overgrowth obscures so much of the wall between the north-west and south-east arcs. A wider break at the north, about 1.5 metres across, appears to be a later cattle break, a practical modification made by farmers who put the sheltered interior to use as pasture, as it remains today. The interior slopes gently southward, and in its northern sector lies a souterrain, an underground passage or chamber typically cut into the ground beneath early medieval settlements, often interpreted as storage space or a place of refuge. Rubble from field clearance has been piled up along the external eastern arc, a reminder that this monument has been embedded in working farmland for generations. To the south, the ground opens out to views across towards Mangerton Mountain.
