This one near Patrickswell, in County Limerick, has none of that. It exists, for all practical purposes, only from the air, and even then only faintly. What lies in a stretch of improved pasture beside a public road is not a ruin in any conventional sense but a cropmark, the kind of ghostly outline that appears when buried archaeological features cause the vegetation above them to grow at subtly different rates. Dry summers tend to make these traces more legible, as shallow-rooted crops stress more quickly over buried stone or compacted earth. This particular enclosure has remained invisible to every historic map surveyor who passed through, recorded neither on the first nor later editions of the Ordnance Survey Ireland maps.

The site was first identified during the Bruff aerial photographic survey in 1986, when the outline of a roughly rectilinear enclosure became apparent from the air. Cropmarks catalogued as Bruff 214 showed a shape approximately 38 metres north to south and 31 metres east to west. Later orthoimage data, captured by Ordnance Survey Ireland between 2005 and 2012, confirmed a very faint version of the same outline, and a Google Earth image taken in March 2017 showed a comparable trace. The enclosure sits about 20 metres east of a watercourse that also serves as the townland boundary with Loughgur, and Lough Gur itself lies just 1.35 kilometres to the northwest. That proximity matters: the Lough Gur landscape is one of the most archaeologically dense areas in Ireland, with Neolithic, Bronze Age, and early medieval remains clustered across its shoreline and surrounding fields. Whether this enclosure belongs to any of those periods is not currently known.

There is no monument to visit in the usual sense. The site is in working farmland and the enclosure is not visible at ground level. The public road to the south of the field does allow a general sense of the location, and anyone with access to Google Earth can locate the faint cropmark from the March 2017 image if they know where to look. The record was compiled by Alison McQueen and Vera Rahilly and uploaded in November 2020, so it remains a relatively recent addition to the formal archaeological inventory. Its interest lies less in what can be seen than in what the aerial record quietly suggests is still there, just beneath the grass.
