The example at Cloonfore in County Longford sits on a low but noticeable hillock in pasture, and what makes it worth pausing over is the precision with which its earthworks have been recorded against the slow erosion they have clearly suffered. A ringfort, or rath, is an enclosed farmstead of the early medieval period, typically circular or oval and defined by one or more banks of earth, occasionally with an outer ditch. Here both elements survive: a raised oval interior measuring roughly 43 metres on its longer axis and just over 30 metres across the shorter one, wrapped by a bank of earth and stone that still stands between 1.1 and 1.7 metres high, despite being partially denuded over the centuries.

The bank itself is substantial, nearly 7 metres wide in places, and beyond it lies an external fosse, the shallow defensive ditch that once helped define the boundary of the enclosed space, running to about 6 metres wide and just over a metre deep. Along the outer edge of this fosse, from roughly the south-east round to the south, fragmentary remains of a drystone-built field wall have been added at some later point, an ordinary agricultural intrusion that speaks to how such monuments have long been absorbed into the working landscape rather than set apart from it. Two narrow gaps in the bank, one at the north-north-east and one at the west-south-west, each accompanied by a causeway crossing the fosse, may represent the original entrance or entrances to the enclosure, though the phrasing of the evidence is careful: these are possibilities rather than certainties, the kind of ambiguity that honest archaeology tends to preserve.
