Ringforts
Sometime between the first Ordnance Survey of Ireland in 1838 and the revised edition of 1931, this ringfort in Rathslevin, County Mayo, disappeared from the map entirely.
It was recorded as an embanked enclosure on the earlier six-inch sheet, then simply omitted from the later one, a small cartographic erasure that says less about the monument's survival than about the shifting attention of mapmakers across a century of change.
The earthwork itself is still there, sitting on a natural rise in pastureland, with the ground dropping steeply to the north-northeast into a hollow of wet ground below. A rath, to use the Irish term, is a ringfort defined by an earthen bank or scarp rather than stone walling, and was typically used as a farmstead enclosure during the early medieval period. This one takes an oval form, measuring roughly 25.5 metres on its northwest-to-southeast axis and 21.7 metres across. The defining scarp, the sloped earthen edge of the platform, varies considerably in height: just 1.8 metres at the southwest but rising to 4.6 metres at the northeast, where the natural fall of the ridge lends it additional drama. The interior holds a slight central rise, with the ground sloping gently southward from there. No entrance survives in any obvious form. The most likely candidate, the southeast side, which faces along the spine of the ridge, has been cut across by a straight field fence running on a northeast-to-southwest line. A low section of the scarp at the west, only about a metre high, offers no clear gap either. Just 135 metres to the west sits a second rath, making this a paired or clustered arrangement of early medieval settlement, which is not unusual in the Irish landscape but always worth noticing.
