Enclosures of this type are among the most common monument categories in Ireland, yet also among the most varied. The term covers everything from the earthen banks of early medieval ringforts, which served as defended farmsteads, to the ditched boundaries of later settlement and agricultural sites. Without further detail it is difficult to say precisely what period or function this particular example belongs to, which is itself a kind of answer about how much of the Irish landscape remains formally unexamined.

Ashglen sits in a county whose soils and river valleys drew settlement from prehistoric times onwards, and Kilkenny as a whole is dense with earthworks, enclosures, and traces of activity that have never been fully excavated or explained. Many such sites survive only as cropmarks visible from the air, or as slight rises and depressions in a field that a passing walker might not register at all. The classification of a site as an enclosure is often the beginning of a question rather than the end of one, a placeholder in the record that acknowledges something is there while leaving its story largely untold.
