It is recorded as a monument, it occupies a named place in the landscape, and beyond that the record falls largely silent. That silence is itself worth noting. Ireland's countryside is threaded with enclosures of various kinds, from the circular earthen raths and ringforts that once served as enclosed farmsteads in the early medieval period, to later field enclosures, ecclesiastical precincts, and settlement remains of harder-to-date origins. Which of these categories the Kilroughil enclosure belongs to is not currently clear from available sources.

Kilroughil as a place-name hints at older layers. The element "kil" derives from the Irish "cill", typically indicating an early church or monastic cell, suggesting that the townland itself may have some ecclesiastical association in its past, though this does not necessarily bear directly on the enclosure as a monument. Clare's landscape holds a considerable density of prehistoric and early historic earthworks, many of them still incompletely studied or published, and an enclosure in this county could belong to almost any period from the Bronze Age onward.
