This one in Raheenduff, County Wexford, makes itself known only from the air, as a faint circular shadow pressed into farmland. What survives is a cropmark, the kind of trace that appears in aerial photographs when buried features alter the growth of crops or grass above them, revealing outlines invisible at ground level. The enclosure is roughly 50 metres in diameter, defined by a single fosse, essentially a ditch that once formed the boundary of a ringfort, the most common type of early medieval settlement in Ireland. Thousands of these circular enclosures were built across the country, typically between the sixth and tenth centuries, serving as farmsteads for families of varying social rank.

The Raheenduff site sits on level ground, which would have made it a workable location for settlement, though the fosse feature recorded in aerial photographs is described as faint, suggesting the original earthwork has been largely flattened over the centuries, most likely through sustained agricultural activity. It does not stand alone in the landscape. A second rath lies approximately 140 metres to the north-west, a pairing that hints at a modest clustering of early settlement in this part of Wexford. Such groupings are not unusual in the Irish midlands and south-east, where ringforts sometimes occur in loose proximity, possibly reflecting family or community ties across generations.
