A cashel is a type of ringfort built from stone rather than earth, essentially a roughly circular enclosure defined by a dry-stone wall, and they are scattered across Ireland in considerable numbers. Most are early medieval in origin, dating broadly from the fifth to the twelfth centuries, and would once have enclosed a farmstead or small settlement. This one carries no great fame, no interpretive panel, no car park. It is simply there, as it has been for perhaps a thousand years or more.

The townland name Clogherrevagh offers a small clue to the character of the place. Derived from the Irish, it suggests stony or speckled rock ground, which is precisely the kind of terrain where stone-built enclosures tended to appear, limestone and fieldstone being ready to hand in a way that made earthen construction secondary. Ringforts of all kinds were the dominant settlement form of early medieval Ireland, and a cashel in a rocky Sligo townland would have been a working farm enclosure, its walls offering protection for livestock and household alike. Beyond that, the particular history of this site remains, for the moment, unrecorded in any accessible public form.
