It measures just 0.7 metres in height and roughly 0.35 by 0.8 metres at its base, with its long axis oriented east to west. Whether it is a genuine standing stone, erected deliberately as a marker or monument, or simply a large stone that ended up vertical by accident or convenience, remains uncertain. That ambiguity is part of what makes it worth noticing.

A rath, for those unfamiliar with the term, is a ringfort, the most common type of early medieval settlement monument in Ireland, typically consisting of a circular area enclosed by one or more earthen banks and ditches. The rath at Brachán is recorded separately, and this small upright stone appears within it, positioned inside the bank to the north-east. Its association with the enclosure raises the possibility that it served some internal purpose, perhaps a boundary marker, a structural feature, or something more ceremonial, though none of that can be said with confidence given how little survives by way of context. The 1997 archaeological inventory for mid Cork logged it carefully but cautiously, flagging it as a possible standing stone rather than a confirmed one, which is an honest reflection of how ambiguous such features can be when found outside their expected setting.
