Ringforts, known in Irish as raths or liosanna, were the most common form of rural settlement in early medieval Ireland, typically consisting of a raised circular area enclosed by one or more banks and ditches. They served as farmsteads for free farming families, protecting livestock and household from wolves and rival neighbours rather than from any organised military threat. That so many survive across the Irish countryside, even in fragmentary form, speaks to just how densely settled the island was during the early medieval period, roughly 500 to 1000 AD.

Listerlin is a small rural townland in the barony of Iverk, a part of Kilkenny that sits close to the River Suir and the Waterford border. The area has a long record of human activity, and a ringfort here would fit comfortably into a wider pattern of early medieval land use across the region. Beyond its location and classification, the specific details of this particular site, its dimensions, its condition, any finds or features associated with it, remain undocumented in publicly available sources at present.
