No wall, no bank, no earthen ring. Whatever once stood or was enclosed here has been absorbed so completely into the landscape that a visitor standing on the spot would have no reason to pause. And yet, for those who read old maps carefully, something is clearly there, or rather, was.

The first edition of the Ordnance Survey six-inch map, produced in Ireland during the nineteenth century as part of one of the most ambitious cartographic projects of its era, recorded this site as a circular enclosure roughly thirty metres in diameter. Enclosures of this general type are among the most common archaeological features in the Irish countryside, ranging from prehistoric ring forts to early medieval farmsteads, and their circular form usually reflected a practical logic of defence and demarcation. Whether this particular example at Gortnalone belonged to any such category is now difficult to say. No surface trace survives. The bogland has done what bogland tends to do, preserving some things absolutely and erasing others entirely, and in this case the earthwork itself appears to have succumbed to the latter process, leaving only its outline on a map sheet drawn by surveyors who arrived just in time to record it before it disappeared.
