This one in Carrowanree, County Wexford, offers nothing of the sort. The small oval embanked enclosure, roughly 35 metres along its longer axis and 30 metres across, is entirely invisible at ground level. Stand in the pasture above it and you would have no idea it was there.

What we know about it comes almost entirely from a single cartographic moment: the 1839 edition of the Ordnance Survey six-inch map, the great early nineteenth-century project that recorded Ireland's landscape in extraordinary detail, capturing earthworks and field boundaries that were already beginning to disappear. On that map, the enclosure is marked sitting at the crest of a low ridge running roughly southeast to northwest, immediately north of a rath. A rath, sometimes called a ringfort, is a circular or oval enclosure typically formed by an earthen bank and ditch, common across Ireland from the early medieval period onward, and usually associated with a farmstead. The proximity of this embanked enclosure to the rath beside it raises the possibility of some functional or chronological relationship between the two features, though nothing in the surviving record settles the question. By the time anyone looked for it at ground level, the enclosure had been reduced to nothing a walker would recognise.
