This one, sitting on a south-east-facing slope in the townland of Tullig in West Cork, is a well-preserved example of the type known as a rath, an enclosure defined not by stone but by earth.

The site takes the form of a roughly circular area, measuring approximately 40.5 metres from north-east to south-west and 39.7 metres from east to west, enclosed by an earthen bank standing around 1.35 metres high. Outside that bank runs a fosse, the term for the accompanying ditch from which the bank material was originally dug, here reaching a depth of 1.3 metres. A causeway crosses the fosse at the northern side, leading to the entrance, which is a modest two metres wide. Raths like this one are generally associated with early medieval Ireland, roughly the period between the fifth and twelfth centuries, when they functioned as enclosed farmsteads for a single family or small farming community. The bank and fosse together served less as military fortification and more as a practical boundary, keeping livestock in and wolves or rival neighbours out. The site sits in pasture, meaning the land around it has continued its agricultural role across the centuries while the monument itself has quietly endured.
