By 1897, however, it had made it onto the revised 25-inch edition, sketched as a roughly circular area some 20 metres across from east to west, defined by a bank running from the south-west, around through the north, and back to the south-east, leaving the southern side open or incomplete. Whatever it once enclosed, it was substantial enough to survive, and ambiguous enough to elude easy classification.

The enclosure sits in reclaimed pasture in the townland of Ballynacaheragh, County Limerick, positioned about 90 metres north of the boundary with Milltown North and roughly 180 metres east of the public road that separates the townland from Lismakeery. Earthwork enclosures of this kind are common enough across the Irish countryside, and the term covers a broad range of structures, from early medieval ringforts used as defended farmsteads to later livestock enclosures or field boundaries of uncertain date. What sets this one apart, at least in documentary terms, is its absence from the first Ordnance Survey record and its subsequent appearance half a century later, which suggests it either escaped notice in 1840, was constructed or became more visible in the intervening decades, or was considered too ambiguous to mark at the earlier date. The record was compiled by Martin Fitzpatrick and uploaded in July 2020, drawing on both the historic map evidence and a Google Earth orthoimage from March 2012 that shows the earthwork still legible as an overgrown circular feature, with faint traces of the enclosing scarp remaining at the southern end.

The site is not formally accessible as a heritage attraction, and because it lies within reclaimed farmland, any visit would require awareness of land ownership and permission from the relevant landowner. The Google Earth imagery gives a reasonable sense of what to expect: a low, vegetation-covered rise describing an arc rather than a complete ring, the southern portion reduced to little more than a shadow in the ground. Those with an interest in field archaeology and a good map will find the townland boundaries useful for orientation, with the public road along the Lismakeery boundary providing the most straightforward reference point.
