Around thirty metres across, it is defined by a narrow wall so thoroughly overgrown that it registers more clearly in aerial photography than it does at ground level, the kind of feature that disappears into the landscape the moment you step off it.

Enclosures of this type are broadly associated with early medieval Ireland, when circular stone-walled enclosures, known as cashels or cahers, served as farmsteads or occasionally as sites of higher social or religious status. The place-name element 'caher' in Caherkinallia itself points in this direction, as does the presence of a related structure nearby. A cashel known locally as 'Caherreagh' lies roughly 118 metres to the east, suggesting that this stretch of ridge once supported more activity than the present emptiness implies. Cutaway bog, the landscape that now surrounds both sites, is the result of industrial or domestic peat extraction that has stripped away the surface layer over generations, leaving behind a terrain that can feel eerily reduced, as though the land has been pulled down a register. That two enclosures should survive within such close proximity of one another, even in degraded form, makes this corner of Clare quietly worth noting.
