In a field of reclaimed pasture in Kilmihil townland, in the barony of Coshlea in County Limerick, an ancient enclosure has been so thoroughly levelled by centuries of agricultural use that the clearest sign of its existence is a faint shadow visible only from satellite imagery, a cropmark caught by Google Earth where the buried remains of the old earthwork affect the growth of grass above it. It is the sort of place that asks you to look twice, and then to look from above.

The enclosure's documented history is one of gradual disappearance. When the Ordnance Survey of Ireland mapped this area at six-inch scale in 1840, the monument appeared as a circular earthwork, the classic form of a ringfort or enclosure of early medieval date, when such structures were commonly built as enclosed farmsteads or places of local significance. By the time the twenty-five-inch revision was carried out in 1897, the shape had already shifted in the surveyors' record to something roughly sub-rectangular, measuring approximately 47 metres north to south and 62 metres east to west. The enclosing bank that once defined it was already poorly preserved along the eastern side and had been reduced to little more than a scarp on the west. The intervening decades of land improvement and pasture reclamation had done their work. The record was compiled by Martin Fitzpatrick and uploaded to the survey database in August 2021.

The site sits around 110 metres east of the road that forms the townland boundary with Tobernea East, and roughly 95 metres south of the boundary with Ballingaddy South. Those boundaries, still visible on modern maps, give the best navigational fix for anyone trying to locate the approximate area. On the ground, there is likely little to see with the naked eye at most times of year; the monument has been largely consumed by the surrounding pasture. Aerial or satellite imagery examined during dry summer conditions, when differential crop or grass growth makes buried features more legible, offers the most reliable view of what remains. It is the kind of place that rewards patience and an appreciation for what archaeology sometimes looks like: not a wall or a tower, but a whisper in the grass.
