That uncertainty is, in its own quiet way, the most interesting thing about it. An enclosure in the archaeological sense is typically a defined area bounded by an earthen bank, ditch, or wall, and such features in Ireland range from early medieval farmsteads to ceremonial or funerary sites. This one, however, is known only from a dashed line on a map, which is the cartographic convention for a feature that the surveyor could see well enough to trace but not well enough to confirm.

The dashed oval appears on the 1882 Ordnance Survey six-inch map, outlining an area of roughly 40 metres north to south and 30 metres east to west. When fieldworkers later visited the site, the undergrowth had become so dense that a proper inspection was impossible. No local memory of the feature appears to have survived either. What remains, then, is a single cartographic gesture made by a nineteenth-century surveyor, a hesitant line that recorded something worth noting without committing to what it was. Whether the underlying feature is a collapsed earthwork, a natural landform, or something else entirely has not been established.
