At Aghafore in County Cork, a souterrain is recorded within a ringfort, yet neither structure announces itself to the eye. The ground gives nothing away.

A souterrain is an underground stone-lined passage or chamber, typically constructed during the early medieval period in Ireland, and associated most commonly with ringforts as a place of refuge or storage. The ringfort at Aghafore, recorded in the archaeological inventory of West Cork, is itself the kind of site that can easily go unnoticed, and the souterrain within it is known only through local information passed down rather than through any formal excavation or visible physical evidence. That the knowledge of it survived at all is largely due to the memory of people living nearby, which is itself a reminder of how much of the archaeological record depends on oral tradition rather than stone or soil.
