The place is called Raheennabaddoge, and it preserves the remains of a rath, the Irish term for a roughly circular or oval enclosure, typically of early medieval date, formed by a raised earthen bank and an outer ditch. These were the enclosed farmsteads of farming families across early Ireland, not forts in any military sense but defended domestic spaces, their banks and ditches marking the boundary between the household and the wider, less certain world beyond.

This particular example is roughly oval in plan, measuring around 34 metres east to west and 25 metres north to south. It is defined by a bank with an external fosse, that is, a ditch cut on the outside of the bank to reinforce the enclosure and make it harder to cross. The fosse does not survive all the way round; what remains runs from the western to the north-western arc of the site. A gap of about three metres on the eastern side may represent the original entrance, which in raths of this type was commonly positioned to face the morning light. The site was noted by Holt in 1912 and recorded again by McCaffrey in 1952, suggesting it has been quietly accumulating scholarly attention across the twentieth century without ever quite breaking into wider notice.
