The structure is a cashel, the Irish term for a ringfort built from dry-laid stone rather than earth and timber, and this one measures roughly 42 metres across. That modest diameter is enough to have enclosed a farmstead, a family, their livestock, and the careful social world of early medieval rural Ireland.

The cashel's drystone wall, built without mortar by placing stone against stone, survives best along its western, northern, and eastern arc, where the original construction is still legible in the landscape. Elsewhere, later hands have complicated the picture. A modern field wall overlies the enclosure on the eastern and south-western sides, the kind of pragmatic reuse that happened across Ireland as farming communities found ready-cut stone wherever they looked. A further field wall runs north to south through the interior, dividing what would once have been a unified domestic space. The site is described as being in fair condition, which, given that drystone cashels are vulnerable to exactly this sort of incremental borrowing and subdivision, is not faint praise.
