At roughly 26 metres north to south and 34 metres east to west, it is a modest enough earthwork, its perimeter defined by a scarp, a steep-edged drop in the ground, that reaches about 0.8 metres in height, though it runs lower on the northern side. Easy to walk past without a second glance, it is the kind of feature that rewards anyone who knows what they are looking for.

Ringforts, known in Irish as raths when they are earthen constructions like this one, were the most common form of enclosed settlement in early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. They served as farmsteads for individual families, the surrounding bank and scarp marking a boundary that combined practical enclosure with social status. What distinguishes this particular example is the presence of a souterrain in its interior. A souterrain is an underground passage or chamber, usually stone-lined, built beneath or adjacent to a ringfort; they are thought to have served as storage spaces, refuges, or both. Their construction required considerable effort, which suggests they were valued features rather than casual additions to a settlement.
