That is, nothing visible to anyone walking the pasture on an ordinary day. Yet beneath the grass of this County Limerick field, the ghost of an ancient enclosure persists, legible only from the air and only under the right conditions, as a pale semi-circular cropmark pressed into the earth like a half-remembered outline.

The enclosure was not recorded on the Ordnance Survey's six-inch map of 1840, suggesting it had already been substantially erased from the landscape by that point, or simply went unnoticed by surveyors working at ground level. It does appear on the later 25-inch OSi map of 1897, recorded as a semi-circular area measuring roughly 35 metres northwest to southeast and 23 metres northeast to southwest. What remained then was a partial bank and fosse, the fosse being the external ditch typically dug to accompany a raised earthen bank, running from the southeast around to the north, with the eastern side entirely open. A drainage ditch intersecting the northern end had further disturbed what little survived. By the time aerial photography was carried out between 2005 and 2012, no surface remains were visible at all. It was only a Google Earth image dated 14 September 2019 that revealed the enclosure's outline again, as a cropmark, the kind of faint discolouration in growing vegetation that betrays buried features below when soil moisture or crop stress differs subtly over disturbed ground. Aerial photographs held by the Aerial Survey of Ireland, reference ASIAP 308/18, taken in October 2002, also document the site. The record was compiled by Martin Fitzpatrick and uploaded in May 2021.

There is another enclosure roughly 60 metres to the west, recorded separately, which gives some sense that this was not an isolated feature in the wider landscape. For anyone visiting the area, the site itself sits in ordinary pasture with no markers or public interpretation. The cropmark is not something a visitor on foot would detect; it is a phenomenon of dry summers and satellite imagery. The most useful approach is to examine the Google Earth orthoimage from September 2019 before any visit, simply to understand what the field once held and to appreciate how thoroughly an earthwork can vanish while leaving its shape encoded just below the surface.
