It is a reasonable-sounding name for something that has, in practice, almost ceased to exist. The enclosure that prompted that tradition is now little more than a faint swelling in the ground, roughly circular, somewhere between eighteen and twenty metres across, with a scarp barely forty centimetres high along its northern and north-western arc. Elsewhere the boundary dissolves into irregular undulations before merging, at the south, with an area of simply rough and uneven ground. A post and wire fence crosses the southern edge, and the surrounding field boundaries that once reinforced the outline have themselves been levelled until they are barely discernible.

What makes this site quietly interesting is the gap between folk memory and the cartographic record. The Ordnance Survey captured this part of Mayo in remarkable detail during its six-inch mapping campaigns of 1838 and again in 1922, yet neither survey marks this enclosure at all. That absence does not mean the feature is modern; it more likely means it was already so reduced by those dates that the surveyors either missed it or judged it too indistinct to record. Enclosures of this general type, when better preserved elsewhere, are often interpreted as raths, the ringforts that served as enclosed farmsteads across early medieval Ireland, typically defined by one or more earthen banks and ditches surrounding a domestic interior. The connection feels plausible here: a closely related rath, a recorded example of precisely that kind of monument, sits just 120 metres to the west, suggesting this corner of Ballinlabaun was once a more populated and organised landscape than the present emptiness implies.
