Roughly 45 metres in diameter and defined by a bank perhaps 10 metres wide, it is the kind of feature that only becomes legible when you know what to look for, or when a satellite happens to pass overhead at the right angle of light.

The enclosure came to attention through aerial and satellite imagery, first reported by researcher Anne-Karoline Distel. It appears on Digital Globe imagery from around 2013, and faintly on earlier Map Genie coverage from 2004 to 2006, as well as on Google Earth images taken in 2021 and 2022. Enclosures of this type, roughly circular areas defined by an earthen bank, are a recurring feature of the Irish landscape and can date to a wide range of periods, from the prehistoric through to the early medieval. The broad bank here, if that is indeed what it is, is consistent with the kind of boundary works associated with enclosed settlements or farmsteads, though without ground investigation the function and date remain open questions. What is certain is that the feature has persisted in the landscape long enough to leave a mark legible across multiple decades of imagery.
