A cashel is a ringfort built from stone rather than earth, the walls raised in dry-stone construction to enclose a defended farmstead, most commonly during the early medieval period between roughly the fifth and twelfth centuries. Thousands of these structures survive across Ireland, yet each one occupies its own particular ground, shaped by the local geology and the practical decisions of whoever chose to build there. Clare, with its limestone-rich terrain, produced more stone enclosures than counties where earthen banks were the easier option.

Ringforts of all kinds were the basic unit of rural settlement in early medieval Ireland, home typically to a single farming family of some local standing. The cashel form, where the enclosing wall could be several metres thick and occasionally survive to a considerable height, offered both a working boundary and a degree of protection for livestock and household alike. In Clare, these structures appear across the Burren and beyond, integrated into field systems that have themselves been layered and reworked over centuries. The Ballygriffy example carries the designation cashel specifically, which points to that stone construction tradition, though the finer details of its current condition, dimensions, and immediate surroundings remain to be fully documented in the public record.
