On a gentle slope of rough scrub and pastureland north of the Drimneen River in County Galway, there once stood a small circular enclosure, roughly fifteen metres across. Today there is nothing to see. The ground gives no sign that anything was ever there.

The enclosure appears on the second edition of the Ordnance Survey six-inch map, published in 1899, marked as a discrete circular feature. Circular enclosures of this kind, sometimes called ring forts or raths, were typically used as enclosed farmsteads or settlement sites during the early medieval period, defined by an earthen bank, a stone wall, or a combination of both. This one, according to local memory, survived into the modern era in a particular form: a dense tangle of overgrowth contained within a low stone wall. That wall was removed in the late 1970s, and with it went the last physical trace of the monument. The hachured linear feature visible on the same OS map immediately to the south-east, which might have suggested further human activity nearby, turns out to be a natural scarp in the landscape rather than anything archaeological.

What makes Carrowndulla quietly instructive is how ordinary its disappearance was. No dramatic excavation, no development controversy; just clearance, at some point in the late 1970s, of what probably seemed like an untidy corner of farmland. The OS map remains the most reliable witness to what was once there, a small circle of ink standing in for a monument that outlasted centuries only to vanish within living memory.
