A cashel is a type of ringfort constructed from dry-stone walling rather than earthen banks, and the form was widely used across Ireland during the early medieval period, roughly the fifth to the twelfth centuries. These enclosures typically sheltered a farmstead and its associated buildings, and in Clare, where limestone is plentiful and close to the surface, stone construction was often the more practical choice.

Ringforts of this kind were once among the most common archaeological monuments in the Irish countryside, with estimates suggesting there were originally around 50,000 across the island. They served as the basic unit of rural settlement for early medieval farming families, and the cashel variant, built from field-gathered or roughly dressed stone, is particularly associated with the west of Ireland. The Ardcarney example belongs to this long tradition, occupying ground in a part of Clare where such monuments are not uncommon, though each one reflects the particular choices and circumstances of its builders.
