That near-invisibility is, in its own way, the most interesting thing about it.

The site is a ring barrow, a form of funerary monument common in Ireland during the Bronze Age, typically consisting of a circular mound or flat area enclosed by a surrounding ditch, known as a fosse, and sometimes an outer bank. When surveyors described it between 1970 and 1972, what they found was a small circular area measuring roughly 8.5 metres east-west and 7 metres north-south, defined by a wide, shallow fosse with the remains of a slight bank along its outer edge. These are modest dimensions, and the earthworks have evidently been further reduced by centuries of agricultural use. The site does not stand alone: two further barrows lie within approximately 15 metres to the east and 14 metres to the north, suggesting this corner of Rathnarrow once formed part of a small prehistoric funerary landscape, clustered together in the low ground while higher, gently rolling pasture rises to the east, south, and west.
