These circular enclosures, known in Irish as raths when defined by an earthen bank and ditch, were the standard farmstead of early medieval Ireland, roughly from the fifth to the twelfth century. Tens of thousands once existed across the island; several thousand survive in some form today, most of them unremarked and easy to miss unless you already know to look.

The place name Lissaniska offers a small clue in itself. The element "liss" or "lis" derives from the Old Irish lios, meaning a ringfort or enclosure, which suggests that the feature here was significant enough to define the entire townland in the minds of the people who named it. That is not unusual in Ireland, where townland names frequently preserve a memory of a structure long after the structure itself has become a grassy mound or a faint cropmark. The rath at Lissaniska is recorded as a monument, which places it within a class of site that once served as the home of a farming family of some local standing, enclosed by one or more concentric earthen banks for reasons that combined practical security with social display.
