The structure is barely legible now: only the basal course of the wall survives, grass- and fern-covered, between 0.2 and 1.1 metres high and around 1.8 metres wide at its northern stretch. The outer face can still be traced all the way around, and is clearest from the south to the south-west, but a later drystone wall was built directly over it from the south-west to the north-east, blurring the original line. The interior face has largely merged with the ground inside. What remains sits within a wider multiperiod field system, and a field boundary that appeared on the 1842 Ordnance Survey six-inch map to the east is still physically present today.

The name, rendered in Irish as Lios Colmáin Bháire, points to a figure called St Colman Baire, who local tradition held had lived within the enclosure. That tradition was recorded in 1839 by John O'Donovan, the scholar and topographer who travelled County Clare gathering place-name evidence for the Ordnance Survey Letters. He noted that a low mound roughly 280 metres to the south-south-east was believed to mark the site of a church also dedicated to Colman Baire, suggesting that the cashel and the putative church formed part of a single early ecclesiastical landscape. Robinson's map of 1977 still named the site Lios Colmáin Bháire, keeping the tradition alive in cartographic form even as the walls continued to settle into the plateau.
