What makes this particular example quietly interesting is not just its age but its layering: a later stone field fence now bisects the interior from north to south, cutting straight through whatever domestic arrangement once existed within the walls. The original enclosure is oval in plan, measuring roughly 37 metres north to south and 29 metres east to west, and what survives is the low foundation course of a stone wall running around its perimeter. It sits approximately 150 metres north-north-west of a second cashel nearby, which suggests this corner of Mayo supported a reasonably dense pattern of early settlement.

The site also contains what may be a souterrain within its interior. A souterrain is an underground stone-lined passage or chamber, typically built during the early medieval period and used for cool storage, refuge, or both. The word is simply the French for "underground," and the structures are found across Ireland in their hundreds, often associated with ringforts of exactly this kind. Whether the one here is intact or accessible beneath the vegetation is unclear; the interior is described as heavily overgrown, and the combination of rock outcrop, encroaching scrub, and the later field division means the original layout takes some effort to read on the ground. The site was recorded as part of an archaeological survey of the Ballinrobe district, including the Lough Mask and Lough Carra area, compiled by D. Lavelle and published in 1994.
