What survives above ground today amounts to a single arc of drystone walling, roughly eleven metres long, curving away at the west-north-west. That is all. The rest of what was once a circular enclosure approximately sixty metres across has been absorbed back into the fields around it, leaving almost nothing for the eye to catch.

A cashel is a type of ringfort defined by its stone construction, as opposed to the earthen bank and ditch of the more common rath. Both are early medieval in character, typically associated with farming settlements dating from roughly the sixth to the twelfth centuries, and scattered in considerable numbers across the Irish countryside. This particular example was significant enough to be labelled simply as "Fort" on the Ordnance Survey Fair Plan, and the first edition of the six-inch Ordnance Survey map recorded it clearly as a circular enclosure. Those nineteenth-century surveys captured something that subsequent generations of agricultural activity have largely erased. The name of the townland, Ardrumkilla, offers a trace of older landscape memory, but the physical structure itself has nearly vanished.

What remains is an unusual kind of presence, a site that is more cartographic than material. The eleven-metre wall fragment is the only tangible evidence that a substantial stone enclosure once stood here, and a visitor unfamiliar with the mapped record would have little reason to pause. For those who do know what to look for, the slight curve of old drystone work against a field boundary is the last legible sentence of a much longer story.
