A suboval ring of stone, roughly 22 metres across at its widest and 17 metres at its narrowest, it survives as a low grass-covered spread between three and three and a half metres wide. At some point after the enclosure fell out of its original use, someone laid a drystone wall along its top, the kind of unmortared field boundary that was being raised and repaired across the Irish countryside for centuries. That wall has since collapsed, and much of it at the north-east has been cleared away entirely, leaving a palimpsest of two different moments of organised land use pressed together in the same few courses of stone.

The enclosure sits within what is described as a multiperiod field system, meaning the surrounding landscape was divided, worked, and reorganised across several distinct phases of human activity rather than in any single period. It was already visible enough to be recorded on the Ordnance Survey six-inch map in 1842, and again on the 1920 edition, which tells us the earthwork was a recognisable feature of the land long before modern archaeological survey. What it was originally built for is less certain. Enclosures of this type in Ireland range in date and function from early medieval settlement to prehistoric stock management, and without excavation the Kilcorney example cannot be pinned to a particular era. What is clear is that it did not stand alone. A cairn, a mound of piled stones sometimes associated with burial, lies roughly 60 metres to the west, and a ring-cairn, a circular arrangement of stones with a hollow interior often interpreted as a monument with funerary or ritual significance, sits about 115 metres to the west-south-west. The three monuments together suggest that this particular corner of the plateau carried some sustained meaning for the people who used it.

A modern farm track runs along the western side of the enclosure, which makes the monument accessible but also underlines how thoroughly the landscape around it has continued to change. The low internal height of around half a metre means the earthwork does not announce itself dramatically; it reads more clearly from a slight distance, where the curve of the stone spread becomes easier to follow against the surrounding ground.
