This one in Dromin South, County Limerick, offers almost nothing to the naked eye at ground level, and yet it is unambiguously there, if you know how to look. An enclosure of some kind once occupied this patch of reclaimed pasture, roughly 25 metres north of the stream that marks the townland boundary with Cloonygarra. It appears on no Ordnance Survey historic map, and by the time aerial orthophotography was carried out between 2005 and 2012, no surface remains were visible at all. Its existence is known almost entirely because of what a camera, pointed downward from an aircraft, happened to catch on a particular afternoon in 1986.

The site was identified during the Bruff aerial photographic survey of that year, recorded as photograph Bruff 25 (AP 5/2112), which revealed the cropmark or soilmark outline of what appeared to be an enclosure. Aerial survey of this kind works by detecting subtle differences in vegetation growth or soil colour that indicate buried features below the surface, patterns invisible at ground level but readable from above. The enclosure sits roughly 160 metres to the northeast of a related earthwork already catalogued in the Sites and Monuments Record as LI039-137---. A Google Earth orthoimage taken on 15 September 2019 shows a shallow circular-shaped depression still faintly present, suggesting some slight topographic trace survives, though it is modest enough to be easily overlooked. The record was compiled by Martin Fitzpatrick and uploaded in May 2021.

For anyone curious enough to seek it out, the location is reclaimed agricultural pasture, which means access depends on landowner permission and the site itself offers very little in the way of visible reward. The depression noted on the 2019 satellite image might be perceptible underfoot or in low, raking winter light when shadows pick out slight variations in ground level, but there is no guarantee. The value of this site lies less in what can be seen and more in what it represents methodologically: an enclosure that survived in the record only because of a single aerial survey flight more than three decades ago, and which might otherwise have gone entirely unnoticed.
