The enclosure measures roughly 16.9 metres north to south and 21 metres east to west, its perimeter wall reduced in most places to about a metre in height, though a stretch of outer facing still survives to the north-north-west, giving a sense of how the whole structure once presented itself to the landscape.

This is a cashel, the term used in Ireland for a ringfort built from stone rather than earthen banks and ditches. Ringforts, which date broadly from the early medieval period, roughly the fifth to the twelfth centuries, were the standard unit of rural settlement across Ireland for several centuries, functioning as farmsteads enclosed against cattle-raiding and opportunistic theft rather than as military fortifications in any grand sense. The cashel form is particularly common in the west and south-west of the country, where loose field stone was easier to come by than the deep topsoil needed for earthwork construction. The interior here is now overgrown, and a natural rock outcrop occupies the northern half of the enclosed area, suggesting the builders worked around the existing geology rather than clearing a flat surface. That practical accommodation between human intention and the underlying rock is one of the things that makes the site quietly legible even in its ruined state.
