A cashel is a ringfort built from stone rather than earthen banks, a circular enclosure whose walls once defined the boundary of a farming settlement, likely that of a single family of some local standing during the early medieval period. Clare is particularly dense with such structures, the karst terrain of the Burren giving builders an almost inexhaustible supply of loose limestone, but each individual cashel tends to slip beneath notice unless something dramatic, a well-preserved wall or a striking hilltop position, draws attention to it.

The Caherlough example belongs to a class of monument that was once so common across Ireland that many were simply absorbed into field boundaries, demolished for their stone, or left to become low grassy rings indistinguishable from the surrounding pasture. Ringforts of all kinds, whether built in earth or stone, functioned as the basic unit of rural settlement in early Christian Ireland, housing farmers, their livestock, and whatever modest wealth a family had accumulated. The cashel form, using dry-stone construction, is found throughout the west of Ireland where suitable stone was close at hand and timber was scarce. Beyond its identification as a cashel in the townland of Caherlough, the specific details of this particular site remain sparse, which is itself a kind of testament to how many such monuments were recorded but never fully studied.
