At Garraun in County Cork, a ringfort once stood with a diameter of roughly 38 metres, its earthen banks enclosing what would have been a farmstead of the early medieval period. A ringfort, or rath, typically consisted of one or more circular earthen banks and ditches surrounding a dwelling space, and for centuries they were a common feature of the Irish countryside. This one has been entirely levelled, leaving no visible trace on the ground today.

The clearest evidence for its existence comes from the Ordnance Survey's six-inch map of 1842, where it appears as a hachured circular enclosure, the small radiating lines indicating raised ground that surveyors in the field could still see and record at that time. Between then and now, agriculture or development removed whatever remained. Its disappearance is not unusual. Thousands of ringforts across Ireland were cleared during the eighteenth and nineteenth centuries as land was put to more intensive use, and many others vanished in the twentieth century. What makes the Garraun example quietly affecting is precisely that the map preserves its outline so plainly, a circle drawn in a landscape that has since forgotten it entirely.
