That is not an accident. Whoever built it read the slope carefully and raised the embankment on the downhill side to keep the interior level, a quiet piece of engineering that still works, more than a thousand years later, in a field in County Limerick.

Ringforts, sometimes called raths, were the most common form of enclosed settlement in early medieval Ireland, typically consisting of a circular area defined by one or more earthen banks and ditches, used to protect a family farmstead and its livestock. This particular example in Corelish West occupies a natural shelf of ground on a gentle east-facing slope, with the land dropping away sharply about ten metres to the north of the monument. The enclosure measures roughly 21 metres north to south and 19 metres east to west. Its bank, nearly eleven metres wide in places, survives best along the northern arc, where the interior height reaches about 0.7 metres and the exterior face rises to 1.2 metres. Elsewhere it has been reduced to little more than a scarp. An external fosse, the defensive ditch that typically accompanied such a bank, can still be traced around the north-western and northern stretches, and remains waterlogged on the south-western side. The present entrance opening faces west-north-west. The site was recorded and compiled by Denis Power, with the record uploaded in December 2013.

The monument sits in pasture and is not formally managed as a visitor site, so access depends on the usual courtesies of farmland. A stream runs along the eastern exterior of the enclosure, which helps orient you on the ground. The southern edge of the ringfort has been clipped by a field boundary running roughly east to west, so the circuit of the bank is incomplete on that side. The interior, levelled by design and kept so by grazing, is entirely grass covered. The northern arc of the bank, being the most intact, gives the clearest sense of the original scale of the earthwork.
