The structure is a cashel, the Irish term for a stone-walled ringfort, oval in plan and measuring roughly 24 metres north to south and 19 metres east to west. What makes it quietly arresting is not any single dramatic feature but the accumulation of detail: the limestone rubble and larger boulders holding their form against the slope, the undulating rocky interior dipping gently toward the south-west, and the presence of a souterrain in the south-east quadrant.

A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement in Ireland, thought to have served for storage, refuge, or both. Their presence within a cashel generally points to domestic occupation rather than purely defensive use, suggesting this enclosure was once someone's home ground. Adding further complexity to the site is a roughly circular annexe, approximately 24 metres in diameter, conjoined to the cashel at the south-west. Defined by its own degraded stone wall, which connects to the main cashel wall at the south and south-west, the annexe has a level interior scattered with moss-covered rocks. Annexes of this kind are not uncommon alongside cashels and may have served as enclosures for animals or as additional working space associated with the household within the main fort. Here, both walls have deteriorated significantly, the annexe boundary now standing only half a metre on either face, giving the whole complex a low, spreading profile that merges almost organically with the surrounding pasture.
