This enclosure in Rathmore North is the kind of site that reminds you how much of Ireland's ancient landscape is only intermittently legible, surfacing and retreating depending on the season, the light, and the lens pointed at it.

The monument sits roughly 420 metres east of the townland boundary with Lacka, in ground cut through by land drains and watercourses, the sort of damp, managed pasture that has been worked and reworked for centuries. It does not appear on Ordnance Survey Ireland historic maps at all, which might suggest it was already too faint to record by the time systematic mapping began. What brought it to official attention was infrastructure rather than archaeology: a Bórd Gáis Éireann aerial photograph taken for the Curraghleigh West to Limerick gas pipeline survey, catalogue number 2497, captured it clearly as a circular earthwork at a scale of 1:5000. The same monument appears on the associated pipeline mapping documentation, referenced as Map 6, Site 6/31. Yet when researchers checked the OSi aerial orthoimage from the 2005 to 2012 survey period, and again on a Digital Globe image from 2011 to 2013, and once more on a Google Earth image from March 2016, the enclosure had become invisible. The site is not alone in that field either; a neighbouring enclosure lies 35 metres to the southwest, and a ring-barrow, a low circular burial mound typically defined by a surrounding ditch, sits 90 metres to the northeast, making this one of three monuments aligned across the same stretch of ground.

Because the earthwork is not visible on standard modern aerial imagery and carries no presence on historic maps, visiting it in any meaningful sense requires knowing exactly where to look. The surrounding land is private agricultural pasture, so access would need to be arranged with the landowner. The notes compiled by Alison McQueen and Vera Rahilly, uploaded to the record in November 2020, reference the Bórd Gáis pipeline photographs as the primary evidence, and those images remain the clearest documentation of the monument's form. Crop marks and soil marks of this kind tend to show best in dry summers when differential moisture in the ground brings buried features to the surface briefly, but given that multiple modern surveys failed to capture it, the enclosure appears to be at the faint end of the spectrum.
