A cashel, the Irish term for a stone-walled ringfort, this roughly circular enclosure sits in low-lying marshy pasture in County Limerick, its ancient boundary wall having been pressed into service as an ordinary field boundary so gradually and so thoroughly that the two are now difficult to tell apart. Ringforts, which were typically enclosed farmsteads built during the early medieval period, are among the most common archaeological monument types in Ireland, numbering in the tens of thousands. Most are earthen. A cashel, built from dry-stone walling rather than banked soil, is the less common variant, and this one in Caheranardrish represents a quietly absorbed example of the type.

The enclosure measures approximately 40 metres north to south and 37.1 metres east to west, forming a sub-circular shape. The wall itself is constructed from un-bonded, un-hewn limestone with a rubble core, and retains rough coursing on its faces, meaning the stones were laid in approximate horizontal rows without mortar binding them. Where the bank survives well, it reaches an internal height of 0.9 metres and an external height of 1.4 metres, with a width of 3.4 metres. The northern to south-western stretch tells a different story: here the bank has been heavily denuded, reduced to a thin trace just 0.35 metres high internally and externally, and only 1.8 metres wide. There is evidence of collapse to the south and north-north-west. A narrow gap in the south-south-west, measuring 1.2 metres wide, may represent the original entrance, though two larger gaps to the north and north-north-west, each around 2 metres wide, have likely opened through erosion and disturbance rather than deliberate design. The record was compiled by Denis Power and uploaded in February 2013.

The site sits in marshy ground, so footwear matters more than most visitors might anticipate, and the approach across the pasture can be soft underfoot depending on the season. The wall is most legible on the better-preserved eastern and southern arc, where the limestone construction is still readable as a structure rather than a field boundary. Fallen trees and scrub partially mask sections of the bank, so some patience is needed to distinguish the ancient stonework from later agricultural additions. The narrow south-south-westerly gap is worth locating, as it offers the clearest sense of where the enclosure was once entered, before the surrounding farmland absorbed so much of what was here.
