There is no ditch, no visible entrance, and the interior is completely level, covered in grass and used to feed livestock. Cattle have churned parts of the bank, softening the edges of something that has quietly persisted for centuries.

The site is a ringfort, or lis, a type of enclosed farmstead that was the standard unit of rural settlement in early medieval Ireland, typically dating from roughly the sixth to the twelfth centuries. The name Lissykeathy preserves that origin, the word lios appearing in anglicised form at the front of the placename. This particular example is modest in scale, roughly twenty metres across internally, defined by a single earthen bank between three and a half and five and a half metres wide. What is unusual here is the absence of a fosse, the encircling ditch that normally accompanies such banks and from which the material to build them was usually quarried. Without one, the bank is relatively low, rising less than a metre and a half on the outer face. Whether the fosse was never cut, or has simply silted and settled beyond recognition, is not recorded.
