The one at Bregoge in north Cork is a different kind of story: it made it through early Christianity, the medieval period, and the centuries of agricultural change that erased so many of its kind, only to be levelled around 1969. A rath, as these enclosures are also known, is a roughly circular earthen bank and ditch that once enclosed a farmstead, typically dating from the early medieval period. This one measured approximately 40 metres in diameter, a modest but respectable size, set on a north-east-facing slope in what is now pasture.

Ordnance Survey maps from 1842, 1905, and 1937 all record it faithfully as a hachured circular enclosure, the standard cartographic shorthand for an earthwork of this kind. The 1842 map adds a telling detail: the interior was planted with trees at that point, a common enough fate for ringforts that had long since lost their domestic function and become inconvenient lumps of ground to farm around. That tree planting may even have helped preserve it through the nineteenth and early twentieth centuries, since earthworks with established root systems are harder to disturb. What survives today is slight: a field fence to the east of the former enclosure incorporates a short section of what was once the eastern bank, now worn down and heavily overgrown. It is, in the most literal sense, a boundary that has forgotten what it was once bounding.
