This ancient fortification sits at the southern end of a north-south ridge, taking advantage of the natural defensive position provided by steep drops to the north and west. The main structure consists of a circular area surrounded by a partially ruined stone wall, originally measuring up to 2.45 metres wide. What makes this site particularly intriguing is the evidence of a second, outer wall; between five and eight metres beyond the inner fortification, individual stones mark out what appears to have been an additional defensive barrier that cleverly incorporated natural rock outcrops into its design.

The interior of the cashel reveals further mysteries about how its inhabitants once lived. The uneven ground surface contains a spread of stones towards the southeast that likely indicates the remains of an internal structure, perhaps a dwelling or storage building. More remarkably, the northwest section of the cashel contains a partially filled souterrain, an underground passage typical of early medieval Irish settlements. This subterranean feature runs for nine metres alongside the inner face of the cashel wall before taking a right-angled turn for another three metres towards the centre of the enclosure.

The souterrain itself showcases the impressive drystone construction techniques of its builders. Where measurements are still possible, the passage measures half a metre wide and 0.6 metres deep below its roof lintels, which sit flush with the ground level of the cashel’s interior. This hidden passageway would have served multiple purposes for the cashel’s inhabitants; providing cold storage for food, a place of refuge during attacks, or perhaps a secure location for valuables. Together with the double-walled defences and strategic positioning, these features paint a picture of a well-planned settlement designed for both daily living and protection in medieval Ireland.
