Not long ago, used to be. The enclosure that appears on a 1924 Ordnance Survey six-inch map as a circular earthwork of roughly forty metres in diameter is now, by all accounts, simply gone, cleared away by a mechanical digger at some point before 2011. When surveyor Denis Power visited and uploaded his findings in August of that year, there was nothing left to see.

Ringforts, also known as raths, are among the most common early medieval monuments in the Irish landscape, typically circular enclosures defined by one or more earthen banks and ditches, and used as farmsteads from roughly the fifth to the twelfth centuries. Thousands survive across Ireland in various states of preservation. The one at Ballynahaha sat on a north-facing slope in pasture land, the kind of quiet agricultural setting where such monuments have often endured for over a millennium, simply because no one had a compelling reason to disturb them. For this particular site, that long stillness came to an abrupt end. Power noted in his survey record that local information attributed the levelling to a mechanical digger, the modern instrument of choice when old earthworks are removed quickly and thoroughly.

For anyone who consults the historic mapping, the 1924 OS six-inch sheet will still show the neat circle at Ballynahaha, a small graphic reminder that the record and the reality can diverge sharply. There is, formally, nothing to visit. The site sits in what was pasture on a north-facing slope, and without any surface trace remaining, there is little to distinguish it from the surrounding ground. Its interest now is almost entirely documentary: a data point in the ongoing and not always encouraging story of how Ireland's early medieval landscape is managed, or not managed, in the agricultural present.
