It is a sub-circular enclosure, roughly twenty metres across, and its most remarkable quality may be how thoroughly it has managed to disappear, not just from the landscape, but from the historical record itself.

An enclosure of this type, a roughly circular or oval area defined by a bank, ditch, or wall, is a common enough form in the Irish countryside. Such features can date from the early medieval period, when ringforts served as farmsteads, or earlier still. But this particular example in Liffane presents a puzzle in the documentary record. When the Ordnance Survey produced its first detailed six-inch map of Ireland in 1840, the feature was not depicted at all. By 1897, a later OS twenty-five-inch map did show a small sub-circular field of approximately twenty metres in diameter on the site, but recorded it as a field boundary rather than an antiquity, suggesting that whoever surveyed it either did not recognise it as something older or chose not to classify it as such. A later Cassini OSi six-inch map records the outline more precisely, measuring roughly twenty-two metres north to south and eighteen metres east to west, again marked with the same solid line used for ordinary field divisions. Orthophotographs taken in 2005 show the outline still visible but surrounded by encroaching scrub. By the time satellite imagery was captured between 2011 and 2015, no surface remains were visible at all. The record was compiled by Martin Fitzpatrick and uploaded in July 2020.

The land around the feature is described as pasture with extensive rock outcropping to the west and north, which gives the surrounding area a characteristically limestone texture common to parts of County Limerick. Because no surface remains are currently visible according to recent imagery, a visit would require some tolerance for ambiguity; this is a place where the interest lies in what the maps suggest rather than what the eye can confirm on the ground. Anyone researching the site would do well to cross-reference the various OS map editions alongside the orthophotograph record, as the progressive disappearance of the feature across those sources is, in itself, the most legible part of the story.
