A circular earthen bank, about 36 metres across and rising to roughly 1.5 metres on its interior face, marks out the boundary of a rath, the common Irish term for an earthwork ringfort. These were the enclosed farmsteads of early medieval Ireland, built and occupied roughly between the fifth and twelfth centuries, and several thousand survive across the country in varying states of preservation. This one is modest in scale but largely intact, with its entrance gap still discernible to the north.

What gives the site particular interest is the possible presence of a souterrain within the interior. A souterrain is an underground stone-lined passage or chamber, typically associated with ringforts and thought to have served variously as a place of refuge, cool storage for dairy produce, or both. They are often only identified through surface subsidence or excavation, which may explain the cautious language around this one. The northern entrance orientation is worth noting too: while ringfort entrances vary, a north-facing opening is less common than eastward-facing ones, and the reasons for such choices, whether practical, social, or cosmological, remain a matter of some debate among archaeologists.
