It sits on a gentle north-west-facing slope in what was once the deer park of Kilballyowen House, within improved pasture interspersed with intermittent woodland, just fifteen metres west of the townland boundary with Knockainy. The trouble is that nobody can say with certainty exactly where it is. It does not appear on Ordnance Survey Ireland historic maps, where the area was recorded under woodland cover, and it cannot be detected on any of the satellite or aerial orthoimages examined between 2005 and 2018. It exists, in the official record, as a potential monument identified from aerial photographs, and the one photograph that might confirm its precise location is missing from the paper file held by the Sites and Monuments Record.

The earthwork was identified through examination of aerial photographs from the GSI Air Photography collection, specifically frames 538 and 539, and an ASI aerial photograph taken on 13 September 2002. That photograph, catalogued as ASIAP 303/26, appears to show something on the slope worth recording, but without access to the original print, the monument's exact form and position remain unverified. The record was compiled by Alison McQueen and uploaded to the national database in November 2020. What is known is that the site sits within a landscape already dense with archaeology: an enclosure lies roughly eighty metres to the north-east, and a ringfort, the kind of circular earthen bank enclosing a farmstead that was common across early medieval Ireland, lies around a hundred and thirty metres to the south-west.

For anyone curious enough to seek it out, the area around Kilballyowen House in south County Limerick is straightforward enough to reach, though the site itself offers no signage or clear public access point. The former deer park is now private agricultural land, so any visit would require landowner permission. The landscape is quietly instructive in itself: the intermittent woodland planting that has grown back over the centuries is precisely what obscured the earthwork from the mapmakers, and the interplay of pasture and tree cover still shapes what can and cannot be seen from ground level or from above. The record remains open, dependent on a photograph that is somewhere in a filing system, unattached to its file.
