A low, curving bank, roughly thirty metres along its arc, rises only a few centimetres above the surrounding ground. In a dry summer it might pass unnoticed; in the wet pasture where it sits, on a north-east-facing slope beside a tributary of the Tralia River, it is the kind of feature that rewards patience and a good eye rather than any dramatic reveal.

A rath is a ringfort, the most common type of early medieval settlement monument in Ireland, typically a roughly circular area enclosed by one or more earthen banks and ditches, and used as a farmstead from roughly the sixth to the twelfth century. What remains here is interpreted as the eastern half of such a structure, the rest presumably lost to centuries of agricultural activity or gradual erosion. The semicircular arc runs roughly north-north-west to south, and its presence was already being recorded on the Ordnance Survey six-inch map of 1894, where the line of the bank is noted running north-north-west to south-south-west. Even then, it seems, this was already a partial thing, a ghost of an enclosure rather than a legible monument. The bank itself is modest: about 4.8 metres wide, with an internal height of roughly ten centimetres and an external height of around twenty, measurements that speak to long centuries of slumping and settling into the soft ground.
