A cashel, the Irish term for a stone-walled ringfort, sits on a south-facing slope of improved pastureland in Newtown, Co. Clare, and while the enclosure itself is faint but traceable, a probable souterrain marked near its centre on an early twentieth-century map has left no visible trace on the ground. A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement and used for storage or refuge. Whatever once existed here has either collapsed, been buried, or merged invisibly with the broader rubble.

The site has a quietly complicated paper history. The first edition Ordnance Survey six-inch map of 1842 recorded it as a confident full circle, the standard cartographic shorthand for a ringfort. By the 1915 edition, that certainty had softened: the enclosure appears only as a partial arc running from north to south-east, and the intriguing addition of a marked 'cave' near the centre had appeared. Whether that cave annotation reflects something observed on the ground at the time, or was inferred from local knowledge, is not recorded. Today the enclosure measures roughly 10.7 metres north to south and 10.1 metres east to west internally, defined by a wide spread of moss-covered stone between 4.7 and 7 metres across and rising no more than 1.2 metres at its highest. Much of this spread appears to be cleared field stone, gathered and deposited over generations of agricultural improvement, which makes reading the original structure difficult. A single internal facing-stone survives at the north, and a possible outer facing-stone at the south. A later field wall runs along the outer western edge, neatly illustrating how working farmland tends to absorb and reorganise whatever came before it. Two further enclosures lie within 270 metres to the north-north-east and east, suggesting this was once a more densely occupied corner of the hillside than it now appears.
