Aerial photography reveals nothing, no earthwork, no visible trace of anything built or dug. Yet the site is listed as a probable rath, the Irish term for a ringfort, a circular enclosure typically defined by one or more earthen banks and ditches, which served as a farmstead or small settlement during the early medieval period, roughly between the fifth and twelfth centuries.

The reason this place is known at all comes down to a single cartographic source. A circular earthwork was recorded here on an estate map of the Barony of Cremorne, drawn by Brownrigg and Longfield in 1790, a document now held in the National Library of Ireland. Estate maps of this period were practical instruments, produced to document landholdings and boundaries, but they occasionally preserved evidence of features that later disappeared through farming, drainage, or the gradual settling of earthen banks back into the soil. Cremorne, a historic barony in south Monaghan, sits in territory that would have supported early medieval settlement, and ringforts are common across the Irish midlands and north, so the identification as a rath is plausible, even if unconfirmed. What the 1790 map captured may be all that survives of it.
