It cannot be seen by anyone standing on the pasture today, yet its outline was clear enough to the cartographers who surveyed the area in 1841, who recorded a roughly circular structure measuring approximately 45 metres across. That it has since vanished from the visible landscape is not simply a matter of neglect; it is the cumulative result of agricultural improvement, reseeding, and the slow erasure of boundaries that once marked its edges.

The 1841 Ordnance Survey six-inch map shows the enclosure already under some pressure, with field boundaries cutting across its north-eastern sector and its northern edge. By the time the twenty-five inch OS map was produced, the monument had disappeared from the record entirely, and the same omission appears on the 1921 revision. What remained for a time was a curvilinear field boundary curving from south-west to north that appeared, on later mapping and on aerial photography taken as recently as 2012, to trace the line of the original structure. Even that boundary has since been removed. The enclosure's name places it in a landscape with a longer memory: "caher" derives from the Irish cathair, referring to a stone fort or enclosed settlement, suggesting the wider townland had a history of such structures. What function this particular enclosure served, and when it was built, is not recorded, but circular enclosures of this kind in the Irish midlands and west are broadly associated with early medieval settlement and farming activity.

The one feature that does survive, of a kind, is a large surface depression sitting slightly off-centre to the east of where the monument once stood. With rock outcrop close to the surface throughout the field, the ground here has clearly not yielded easily to the plough, and that slight hollow may be all that now marks a structure that was already being absorbed into the agricultural landscape nearly two centuries ago.
