While earthen ringforts were built from the soil at hand, a cashel reflects the local geology directly, its walls raised from the same fractured limestone that defines the Burren landscape. That the two terms, ringfort and cashel, appear together in the site's designation hints at a classification question that fieldwork alone could resolve.

Cashels of this kind were typically built and occupied during the early medieval period, roughly between the fifth and twelfth centuries, and served as enclosed farmsteads for a single family or small kin group. In the Burren region of Clare, where tillable soil is scarce but stone is everywhere, cashels are relatively common features of the landscape, their circular walls sometimes still standing to considerable height. Bealnalicka itself is a small townland, and the presence of a cashel there is a quiet reminder that this apparently empty limestone plateau was, for centuries, a working agricultural landscape with a settled population.

The Burren's cashels are often easier to appreciate from a distance than from within, where the enclosure can be difficult to read. The limestone pavement and scrub vegetation of the area mean that approaching any individual site requires care, and many survive in varying states of preservation, from near-complete circuits of walling to spreads of collapsed stone that only reveal their circular logic on closer inspection.
