At Atticoffey in County Galway, a ringfort once occupied the rounded crest of a drumlin, one of those smooth, egg-shaped hills of glacial till that give this part of the Irish midlands its lumpy, rolling character. Ringforts, roughly circular enclosures defined by earthen banks and ditches, were the dominant form of rural settlement in early medieval Ireland, used variously as farmsteads, cattle enclosures, or defended homesteads. The one at Atticoffey measured approximately forty metres in diameter, a modest but not insignificant size. Today, no visible surface trace survives.

What makes this site quietly compelling is the paper trail it leaves. It appears on the Ordnance Survey Fair Plan, the detailed working documents produced during the great nineteenth-century mapping of Ireland, where it is marked simply as 'Fort', a label that at least confirms local recognition of the feature at the time. It was still recorded as a circular enclosure on the third edition of the six-inch Ordnance Survey map, published in 1947, suggesting it was at least partially legible in the landscape within living memory. Somewhere between that mid-twentieth-century survey and the present, the last surface evidence was lost, most likely to agricultural improvement or ploughing. The drumlin remains. The fort, for all practical purposes, does not.
