At Templenoe in County Cork, a roughly circular enclosure measuring around 43 metres north to south and 41 metres east to west sits on a south-facing slope, its presence announced by that characteristic tree-lined earthwork rising about 1.5 metres above the interior ground level.

This is a rath, the Irish term for a ringfort, the most common monument type in the Irish landscape. Thousands were built between roughly the early medieval period and the early Christian era, typically serving as enclosed farmsteads for a single family or extended household. The surrounding bank and its external fosse, a defensive ditch, were as much a statement of social status as a practical barrier. At Templenoe, the fosse is notably well-defined, with steep sides, a flat base some four metres wide, and a maximum depth of 1.8 metres. A causewayed entrance, a deliberate uncut gap in the ditch to allow passage, faces south at 2.2 metres wide. The interior itself slopes gently downward toward that same southern aspect, which would have offered both shelter and reasonable drainage for whoever once lived within.
