In a pasture at Ballymorisheen in mid Cork, a slight rise in the ground is almost the only evidence that a ringfort once occupied this spot. A ringfort, or rath, is a type of enclosed farmstead, typically circular and bounded by one or more earthen banks and ditches, built during the early medieval period and once numbering in the tens of thousands across Ireland. This one measured roughly 35 metres in diameter, a modest but not unusual size, and survived long enough to be mapped repeatedly before disappearing within living memory.

The enclosure appears on Ordnance Survey six-inch maps from 1842, 1904, and 1938, each time rendered as a hachured circle, the standard cartographic shorthand for an earthwork with sloping banks. That it was faithfully recorded across nearly a century of mapping suggests the feature remained reasonably intact well into the twentieth century. According to local information, however, it was levelled around 1980, almost certainly to make the land more workable for agriculture. The timing is not unusual; the decades following Irish land consolidation schemes saw the removal of many ringforts across the country, often without any prior archaeological investigation. What remains at Ballymorisheen is a faint swelling in the pasture, the compressed ghost of the original bank, still just perceptible underfoot and from certain angles of light.
