That kind of pairing is not unheard of in the Irish landscape, but it is unusual enough to give pause. The more northerly of the two, set into gently rolling ground at Tonacooleen, has survived in reasonably good condition despite the pressures working against it.

A rath is an early medieval enclosure, typically circular, formed by earthen banks and ditches and understood to have served as a farmstead for a family of some local standing. This one measures 34 metres in diameter and is defined by two banks with a fosse, the term for a ditch dug between them, running between. The inner bank has held up best along the southern arc, from the south-east around to the south-west, while elsewhere the enclosure is marked by a scarp, a slope in the ground rather than a built-up bank. A well-defined entrance gap survives on the northern side. Quarrying, however, has eaten into the monument from the west around to the north, removing whatever earthworks once stood in that sector and leaving a partial ruin of what was once a complete circuit. Immediately to the south, a second ringfort survives, the two monuments occupying the same small stretch of countryside in a configuration that would once have made this a place of some local significance.
