What marks it out is not its current state but what it once was, and what still survives beside it. Resting on the field wall immediately to the west of the ruin lies a portion of the upper disc of a rotary quern, the grinding stone of a hand-operated mill used to process grain. The fact that it is still there, set casually into a wall rather than carried off or buried, gives the site an almost domestic quality, as though whoever last used it simply set it down.

The structure itself is a clochaun, a type of dry-stone beehive hut built without mortar, characteristic of early medieval Ireland and particularly associated with the Dingle Peninsula, where examples survive in various states of preservation. This one is marked on Ordnance Survey maps but has largely fallen in on itself, leaving only traces of what the original building would have looked like. The site was recorded as part of the Corca Dhuibhne archaeological survey published by J. Cuppage in 1986, a systematic effort to document the remarkable concentration of early monuments across the peninsula. The quern fragment beside it suggests the site was once part of a working landscape, somewhere grain was grown, processed, and consumed, rather than a purely ceremonial or ecclesiastical location.
