This one, on flat pasture in Glenogra, County Limerick, does no such thing. It exists, for most practical purposes, as a slight unevenness in a field, a faint circular outline that shows up best not to the naked eye but in aerial photography and satellite imagery taken decades apart. It never made it onto the Ordnance Survey Ireland historic maps at all, which means generations of cartographers passed over it entirely.

The site came to wider attention through a Bruff aerial photographic survey carried out in 1986, recorded as Bruff 100.2 (AP 4/3598). Aerial survey has long been one of the more reliable tools for identifying enclosures, the circular or oval earthworks, defined by banks and ditches, that were used throughout early medieval Ireland as farmsteads, settlement boundaries, or places of ritual significance. What the 1986 survey caught from the air was later corroborated by an OSi orthoimage from 2005 to 2012 and by Digital Globe orthoimages taken between 2011 and 2013, all of which show the faint circular outline that is thought to be the surviving trace of the enclosure. A Google Earth image from 28 June 2018 captures the uneven ground on the surface. The site sits roughly 18 metres north of the townland boundary with Coolfune, and it is not alone in this landscape: a second enclosure lies approximately 125 metres to the west, and a third around 220 metres to the west-northwest, suggesting a cluster of activity in this otherwise unremarkable stretch of south Limerick farmland. The record was compiled by Edmond O'Donovan and uploaded in October 2020.

Visitors should not expect a dramatic earthwork. The site is on private agricultural land, and there is no formal access or signage. The enclosure is genuinely difficult to read at ground level, and the most legible versions of it remain the aerial and satellite images held in the archaeological record. Anyone with an interest in how such sites are identified and documented would do well to look at the Bruff survey image alongside the Google Earth orthoimage before visiting, simply to calibrate expectations. The surrounding pasture is flat, the landscape quiet, and the cluster of three enclosures in close proximity is the detail that gives the place its quiet archaeological weight.
