Beneath the practical agricultural boundary lies the remnant of a cashel, a type of ringfort built from stone rather than earthen banks, and the circular raised area it defines measures roughly 24 metres across. On the eastern side, where a gap in the enclosure marks what was likely an original entrance, a large recumbent stone still lies on the southern edge of the opening, about 90 centimetres long and 60 centimetres high. It is the kind of detail that is easy to miss but hard to explain away.

Ringforts, whether built of stone or earth, are among the most common early medieval monument types in Ireland, typically associated with enclosed farmsteads dating from roughly the fifth to the twelfth centuries. A cashel specifically uses dry-stone walling to create that enclosure, and they are particularly characteristic of the rocky landscapes of Munster. This example sits atop a knoll on the west-facing slope of the Caha River valley, in rough pasture that has clearly seen centuries of agricultural use. The northeast quadrant contains a field clearance cairn, a pile of stones gathered from surrounding land to make cultivation easier, and the interior of the enclosure is crossed by cultivation ridges running east to west. Those ridges indicate that the enclosed ground was worked as tillage at some point, long after the original function of the site had been forgotten or abandoned. The fort, in other words, became a field.
