An enclosure once stood here, or almost certainly did, and the only sustained evidence for it comes from a sequence of Ordnance Survey maps that disagree, subtly but significantly, about its shape.

The first edition six-inch OS map, surveyed in 1839, records a tear-drop-shaped enclosure roughly 42 metres north to south and 20 metres east to west, tapering as it runs southward. By the time the 1900 revision was produced, and again on the larger 25-inch OS map, the same feature had been rendered as roughly semi-circular, smaller in extent and clipped along its eastern edge by the stream beside it. Enclosures of this kind, broadly circular or ovoid earthwork boundaries, are common across the Irish landscape and typically associated with early medieval settlement, though they can also reflect field boundaries, burial grounds, or other organised use of land across a wide span of time. What the two Ordnance Survey depictions suggest is either that the feature changed between surveys, that different surveyors interpreted a degraded earthwork differently, or both. When the site was visited in 1987, a quarry occupied the location, offering no clear trace of what the maps had recorded. Today the area is covered in forestry, and whatever earthwork may once have defined this wet, marginal ground is, for practical purposes, gone.
