Enclosures
On a ridge in Shanclogh, County Mayo, a small earthwork was once substantial enough to be carefully recorded by the Ordnance Survey, then quietly vanished from the maps, and finally from the ground itself.
The 1838 OS six-inch map shows a circular embanked enclosure, somewhere between fifteen and twenty metres across, sitting on a northwest to southeast ridge amid what is now open pasture. By the time the twenty-five-inch plan was made, the feature had already shifted in character, recorded as a D-shaped hachured form, roughly twelve to fifteen metres on its longer axis and about eight metres on the shorter, with a field boundary running along its straight northwestern edge. By the 1930 edition of the OS six-inch map, it had disappeared from cartographic record entirely. Today, there is no visible trace on the surface at all.
What exactly this feature was remains genuinely uncertain. It may have been a ringfort, the most common type of early medieval enclosure in Ireland, typically a circular earthen bank defining a farmstead or high-status residence. But it is equally possible that it was a barrow or mound, a prehistoric burial monument, which would place it in an entirely different category of human activity and period. The change in shape between the two map editions, from circular to D-shaped, might reflect gradual erosion, agricultural disturbance, or simply the differing conventions of surveyors working at different scales. The field boundary along its straight side suggests that, at some point, the enclosure was incorporated into a working agricultural landscape, which may have hastened its disappearance. Without excavation, none of these questions can be resolved, and the ground itself offers no answers now.
