In Ballynacarhagh, County Clare, a pair of circular earthworks occupy a south-facing slope near the top of a hill, one slightly uphill, the other close behind it to the south-south-east, both now hemmed in by commercial conifer planting. A ringfort, or rath, is a roughly circular enclosure defined by an earthen bank and ditch, used in early medieval Ireland primarily as a farmstead and boundary marker for a family of some local standing. Finding two in such close proximity raises questions about the social geography of whoever farmed this wet, hilly ground well over a thousand years ago.

The rath at Ballynacarhagh is modest in its surviving dimensions: a circular enclosure about 26.5 metres in diameter, defined by a low, round-topped earthen bank about 2.5 metres wide. Internally the bank rises only around 0.2 metres above the enclosed ground, and 0.4 metres on the outer face, with a flat-bottomed waterlogged fosse, or ditch, running around the outside at about 2 metres wide. These are subtle earthworks, easy to overlook, and the site has clearly absorbed the pressures of agricultural use over generations. Multiple cattle gaps have been cut through the bank, and a field boundary that once divided the eastern half of the interior has since been levelled. The site was already recorded on the 1916 edition of the Ordnance Survey six-inch map, though at that point it was marked simply as an enclosure rather than identified as a rath. Trees have since been planted directly up to the fosse along its northern and eastern edges, compressing what would originally have been an open setting.

The surrounding land is hilly, undrained marshy pasture, which gives some sense of the marginal but defensible quality of the position. The clearing within the plantation where the rath sits offers just enough open ground to see the earthworks, and a photograph taken from the south-west shows both this rath and its near neighbour visible in the same frame, which underlines how unusually close together they are. Whether the two enclosures were contemporary or represent successive occupation of the same hillside is not recorded, but the pairing is the detail that stays with you.
