What little is known about it comes not from anything a visitor could see on the ground, but from a photograph taken from the air, decades after the last ground-level evidence had vanished.

The Ordnance Survey's third edition six-inch map, published in 1933, recorded the feature as a small circular mound roughly ten metres in diameter. That might have been the end of it, filed away as an earthwork of uncertain character. Then, in July 1970, aerial reconnaissance carried out under the Cambridge University Committee for Aerial Photography, reference CUCAP BDN 81, resolved the shape more clearly: a circular feature defined by a double-faced stone wall, the two outer skins of a wall with a rubble or earth fill between them, a construction method associated with domestic and enclosure architecture throughout early medieval Ireland. The tentative identification is that of a house, though the date remains entirely unknown. No visible surface trace survives today. Roughly fifty metres to the south-west lies a ringfort, GA057-134, one of the ring-shaped enclosed farmsteads that were the standard rural settlement form in Ireland from roughly the fifth to the twelfth centuries. Whether the two features are related in date or use is unrecorded, but their proximity on that quiet rise is suggestive of a landscape that was once, in some form, inhabited and organised.
