This one in Kildromin, County Limerick, does neither. It exists, to most eyes, as a faint irregularity in a wet, drained field, and for much of its recorded life it has appeared only when viewed from the air, in the right season, under the right conditions. Even then, it is not always there.

The site was first formally identified during the Bruff aerial photographic survey of 1986, when a semi-circular cropmark, open to the north-north-east, appeared in survey image Bruff 161 (AP 4/3633). Cropmarks form when buried features, such as ditches or banks, affect the growth of overlying vegetation, making them readable from above even when invisible at ground level. The enclosure does not appear on any Ordnance Survey Ireland historic maps, which suggests it either escaped earlier cartographic notice or was already too degraded to register by the time systematic mapping was underway. By the time modern orthoimages were compiled between 2005 and 2012, the original semi-circular cropmark had vanished entirely, though a related oval-shaped earthwork measuring roughly 23 metres north-west to south-east and 20 metres north-east to south-west, defined by what may be a low bank, was visible a short distance to the south-east. A ditch-barrow, a circular monument typically defined by a ditch rather than a mound, lies around 162 metres to the south-west, and the whole area sits approximately 200 metres south-west of the townland boundary with Milltown. The record was compiled by Alison McQueen and Vera Rahilly and uploaded in November 2020.

The surrounding land is low-lying wet pasture, cut through by drainage channels and watercourses, which makes casual access difficult and conditions underfoot unpredictable. There is nothing to see in the conventional sense; no upstanding masonry, no interpretation board, no visible earthwork that would read as such without prior knowledge of what to look for. What remains of interest here is the methodological point the site quietly illustrates: that aerial survey continues to recover traces of settlement and enclosure that ground-level fieldwork and historical mapping entirely missed, and that the same site can look entirely different depending on the year, the season, and the resolution of the image consulted.
