Once into the earth, swallowed by gorse and reeds until a field inspection in May 1999 found no visible trace of it whatsoever. And then again into obscurity, known mainly through the ghost of a line drawn by an Ordnance Survey cartographer in 1842 and, more recently, through the faint outline visible in aerial imagery captured by satellite in March 2020.

The 1842 edition of the six-inch Ordnance Survey map marks the site with hachures, the cartographic shorthand used to indicate an earthwork or enclosure, showing a roughly subcircular form measuring approximately 50 metres on its northwest to southeast axis and around 47 metres northeast to southwest. That is a substantial footprint, comparable in scale to many ringforts, the circular enclosed farmsteads that were the dominant settlement form in early medieval Ireland. The setting is a particular one: the enclosure sits at the base of a steep south-facing hillock in marshy pasture, immediately north of a stream, with steep hills pressing in on all sides. It is the kind of low, sheltered, waterside position that recurs in the Irish landscape wherever people once chose to settle close to a reliable water source.
