Most of Ireland's estimated fifty thousand ringforts were constructed from thrown-up earth and timber, so a cashel, using stacked unmortared stone, represents a variation shaped largely by local geology and the availability of good building material. That this one survives in any form at Ballymihil is itself notable, given how many such structures have been levelled by centuries of agricultural improvement.

Beyond its classification and location, the documentary record for this particular site is, for now, thin. What can be said is that cashels of this type served as the basic unit of rural life in early Christian Ireland, enclosing a family's dwelling house, outbuildings, and livestock against both the elements and opportunistic raiding. The stone wall, sometimes several metres thick at its base, was practical rather than purely defensive. Clare, with its limestone-rich landscape, produced a number of these stone enclosures, and Ballymihil sits within a county that has long rewarded those who look carefully at field boundaries and slight rises in otherwise ordinary ground.
