Enclosures of this kind are among the most common and yet most enigmatic features of the Irish countryside. The term covers a broad range of structures, from the circular earthen banks of a ringfort, which would have enclosed a farming settlement in the early medieval period, to later field boundaries and ceremonial or funerary enclosures reaching back into prehistory. Without further documentation, Ballyroe's example keeps its own counsel.

The townland name itself offers a small clue to the texture of the place. Ballyroe derives from the Irish Baile Rua, meaning the red townland or homestead, likely a reference to soil colour or vegetation rather than anything more dramatic. Kerry's landscape is dense with archaeological features of this kind, many of them unexcavated and known only by their surface profile, a slight rise in a field, a curve of bank and ditch that a passing eye might easily read as a natural contour. That so many survive at all owes much to the persistence of pastoral farming, which tends to preserve earthworks that tillage would long since have levelled.
