This one in Clooncorraun, a townland in County Mayo, offers nothing of the sort. The enclosure has been levelled entirely, and a visitor walking the undulating cleared pasture today would find no visible trace that anything was ever there. What makes it quietly strange is precisely that absence, and the paper trail of maps and photographs that keeps pointing to a place that has, on the ground, ceased to exist.

The site appears on the 1838 Ordnance Survey six-inch map as a circular enclosure, the kind of enclosed area, likely defined by an earthen bank or wall, that recurs throughout the Irish landscape as a remnant of early medieval settlement or agricultural use. By the time the 1929 Ordnance Survey revision was made, the record had become more detailed: a roughly oval walled enclosure, approximately 40 metres north to south and 35 metres east to west, with its interior bisected slightly to the north-east of centre by a wall running on a north-west to south-east axis. An aerial photograph also captured the site, preserving at least its outline. At some point between the mapping and the present, the whole thing was levelled. A further complication arises from Lavelle's 1994 Archaeological Survey of Ballinrobe and District, which recorded an oval-shaped mound of clearance material nearby, roughly 38 metres in diameter and standing 2.3 metres high, and suggested it might overlie the enclosure's remains. In reality, that mound sits about 45 metres to the south-east, a separate feature that has been confused with the enclosure itself in at least one published account.
