It is the kind of archaeology that exists primarily as a shadow.

The aerial photograph that brought this site to attention shows the cropmark of a large circular enclosure defined by two concentric fosses, which are ditches dug into the earth, typically thrown up around a settlement or ceremonial space. The site sits on the crest of a roughly east-to-west ridge, with the ground falling away to the north and south and the ridge end dropping off to the east, a configuration that would have given any early medieval occupant both good drainage and a natural command of the surrounding terrain. Within the enclosure, traces of internal detail are just visible, including a linear fosse that may mark the line of a souterrain. A souterrain is an underground stone-lined passage or chamber, constructed during the early medieval period in Ireland, and used variously for storage, refuge, or as a cool larder. The suggestion of one here is tentative, inferred from a shadow in a photograph rather than confirmed by excavation, which gives the site a quality somewhere between a discovery and an open question.
