This is a cashel, the Irish term for a stone-walled ringfort, and the way its north-eastern corner has been rounded and drawn back to follow the ravine's edge gives the impression of a structure that grew into its landscape rather than being imposed upon it. Moss covers the older, fallen core of the perimeter wall, while a later drystone construction sits on top of that collapse, reaching just over a metre in height on the exterior at its tallest northern stretch. The overall enclosure measures roughly 33 metres north to south and 30.5 metres east to west.

What makes the site particularly layered is not the cashel wall alone but what survives inside it. Against the eastern wall, an irregular structure appears on the 1920 Ordnance Survey six-inch map under the name 'Ancient Dwelling', a label that carries a certain unintentional charm given that almost everything here is ancient by most standards. A possible house site occupies the south-western corner of the interior, and a small cairn, a modest heap of stones whose purpose is unrecorded, rests against the southern wall. The cashel itself was already plotted on the 1897 OS twenty-five-inch plan, though for much of the twentieth century it was catalogued simply as an 'Enclosure' in the Record of Monuments and Places. The site sits within a large multiperiod field system, meaning the landscape around it shows evidence of human organisation and use across several distinct periods, the cashel being one layer among many pressed into the same ground.
