This one is notable, in a quieter way, for how little can actually be confirmed about it. A potential enclosure on flat pasture in Glenogra, County Limerick, sits at the edge of the townland boundary with Ballycullane, and its very existence remains a matter of cautious uncertainty. It appears on no Ordnance Survey historic maps, and repeated examination of aerial and satellite imagery spanning more than a decade has failed to pin it down with any confidence.

The site came to attention through the Bruff aerial photographic survey of 1986, when a photograph, referenced as Bruff 100.3 (AP 4/3598), suggested the presence of a circular or sub-circular enclosure, the kind of earthwork, usually defined by a bank and ditch, that was commonly used in early medieval Ireland as a farmstead boundary, known more broadly as a ringfort. The external dimensions noted at the time were approximately 14 metres, which would make it a relatively modest example. Crucially, however, a handwritten comment on a copy of that photograph acknowledged the site as unclear on the aerial print itself, a caveat that has only grown more significant over time. Orthoimages captured by the Ordnance Survey of Ireland between 2005 and 2012, Digital Globe imagery from 2011 to 2013, and successive Google Earth captures up to June 2018 have each failed to resolve the question. A confirmed enclosure recorded under the reference LI031-197 lies some 360 metres to the southwest, offering a point of comparison, but the Glenogra site remains unverified. The record was compiled by Edmond O'Donovan and uploaded in October 2020.

For anyone interested in visiting the general area, the site lies on flat agricultural pasture, which means there is little in the way of visible topography to guide the eye even on the ground. The townland boundary with Ballycullane provides a rough orientation point. Given that the feature has not shown up reliably under various lighting conditions and seasons in aerial photography, a visitor should not expect to identify anything obvious from field level. What makes this place worth knowing about is less what you might see and more what the record itself illustrates: the painstaking, often inconclusive work of documenting a landscape where centuries of farming, drainage, and land use have reduced possible ancient features to the faintest of traces, legible briefly from the air in 1986, and elusive ever since.
