That sequence of erasures is what makes this site quietly odd: something was considered significant enough to record in 1811, yet by the time the Ordnance Survey began its systematic mapping of Ireland in the 1830s, no trace of it warranted inclusion.

The enclosure first appears on an estate map of 1811, drawn at a time when landowners were documenting their holdings in considerable detail. It does not appear on the OS six-inch maps of 1838 or 1920. When the site was visited in 1998, only the western half of the structure remained even faintly legible on the ground, measuring roughly 20 to 25 metres north to south and around 11 metres east to west. An enclosure, in this context, typically refers to a roughly circular or oval earthwork, often a raised bank with an internal ditch, that might have served as a farmstead, a place of assembly, or a ritual site in early medieval Ireland. The eastern half had vanished entirely, its outline cut across by a later straight field wall running north to south. The surrounding ground is level and scattered with limestone boulders, with a rocky limestone outcropping rising immediately to the north-east, the kind of terrain that has likely shaped and reshaped human activity in this corner of Mayo across many centuries. A forestry plantation now covers the location, adding one further layer of obscurement to a site that had already been disappearing incrementally for at least two hundred years.
