A circular enclosure once stood in the fields of Lissanearla in north County Kerry, two fields to the north-east of a neighbouring rath of the same townland name. A rath is an earthen ringfort, a type of enclosed farmstead built across Ireland roughly between the early medieval period and the Norman arrival, typically consisting of a raised bank and ditch encircling a domestic space. This one left no mark on the ground at all, though it was once real enough to be mapped.

When the Ordnance Survey recorded the area in 1841 and 1842, the enclosure was clearly visible and duly noted. By the time the revised edition appeared in 1898, something had already begun to erase it: a fieldbank running in a north-east to south-west direction had been cut through the northern sector of the site. The practical needs of farming, dividing land into workable parcels, had begun to overwrite the older geometry. At some point after that, the remainder disappeared entirely, and today no surface trace survives. The site exists now only as a reference in the cartographic record and in C. Toal's North Kerry Archaeological Survey, published in 1995, which catalogued it alongside its better-preserved neighbour.
