Rather than running straight, it kinks outward, bending around something older than itself, something the farmer who laid the boundary evidently thought it wiser to skirt than to disturb. That something is a ringfort, a type of enclosed circular settlement used across Ireland from roughly the early medieval period, and the field boundary has, in effect, been quietly preserving the outer edge of its fosse for generations without most people noticing.

The site consists of a roughly circular area approximately twenty metres in diameter, enclosed by two concentric earthen banks separated by a wide intervening fosse, the ditch between them measuring nearly six metres across. The inner bank survives to an external height of around 0.9 metres, though it is heavily masked by overgrowth, while the outer bank, lower at around 0.3 metres externally, is best preserved along its south-east to west-south-west arc. There is a break in the outer bank between east and south-east, matched by a corresponding dip in the inner bank slightly further round, which may indicate the original entrance to the enclosure. The site sits near the base of a gentle east-facing slope, in ground that is notably marshy, a setting that would have made the double-bank and fosse arrangement particularly effective as a boundary and drainage feature. The record was compiled by Denis Power and uploaded in August 2011.

Accessing the site requires some tolerance for wet ground and dense vegetation. The interior is completely covered by overgrowth, so there is little to see inside beyond what imagination supplies. The outer bank, where it survives most clearly along the south-eastern arc, is the most legible part of the structure, and the kink in the adjacent field boundary is arguably the clearest indication that something is there at all. Visiting in late autumn or winter, when vegetation has died back, gives the best chance of reading the earthworks. The fosse, at just over a third of a metre deep, is not dramatic on the ground, but its width and the double-bank arrangement are more visible once you know what to look for.
