It would be easy to walk across it without noticing anything at all, and yet the ground holds the faint memory of a structure that was already old enough to be mapped by the Ordnance Survey in 1839, when it was recorded as an embanked enclosure roughly 25 metres across in both directions, its southern edge already cut through by a lane running roughly west-northwest to east-southeast.

The site sits at the bottom of a valley, with the headwaters of a small stream just to its south, a location that would have been typical for a rath, the kind of roughly circular or oval earthen enclosure, usually defined by one or more banks and ditches, that was the standard form of enclosed farmstead in early medieval Ireland. Whether this particular enclosure actually functioned as a rath is uncertain; the possibility is noted, but the evidence has not resolved the question. By the time the first detailed Ordnance Survey maps were being drawn in the 1830s, the lane had already truncated its southern arc, and by now the banks themselves have largely flattened, leaving only that slightly dished ground surface of around 30 metres in diameter, grass-covered and easy to misread as a natural hollow.
