The name itself is telling. Where a ringfort built primarily of earth and timber is generally called a rath, a cashel is its stone-built equivalent, a roughly circular enclosure whose walls were constructed from dry stone or mortared rubble rather than banked soil. The "cahereen" label suggests that local memory of this structure has persisted long enough to acquire its own intimate shorthand, even as the walls themselves have settled and spread.

The enclosure is subcircular in plan, measuring approximately 42.3 metres north to south and 48 metres east to west, dimensions broadly consistent with a single farmstead cashel of early medieval date, though the notes assign no specific period. What survives of the perimeter wall still stands to around 1.2 metres in places, built in coursed rough stone with a rubble and earth core, a construction technique common to cashels across Munster. The wall runs from the north-north-east round to the north-west; the remaining arc to the north is now formed by a modern field fence, which in places sits directly on top of the original stonework. Gaps appear in the north-north-east and north-east sectors of the enclosure, possibly original entrances, possibly later breaches made for agricultural convenience. The two are not always easy to distinguish once a site has been in continuous pastoral use for centuries.
