This ringfort, known locally as a rath, measures 33 metres across its interior and is surrounded by a low earthen bank with faint traces of an outer defensive ditch, or fosse. The western side once featured a 6-foot-wide entrance gap aligned with a 9-foot-wide causeway, providing access to this ancient fortified settlement.

Today, a modern field fence bisects the interior, but the site’s defensive features remain clearly visible in the landscape. Ringforts like this one served as fortified farmsteads for prosperous families during the early medieval period, roughly from 500 to 1200 AD. The earthen banks would have been topped with wooden palisades, whilst the interior likely contained timber buildings including dwelling houses, storage structures and animal pens.

The Cherrymount ringfort appears to be part of a larger archaeological complex, with two other recorded sites nearby (catalogued as DG107-071 and DG107-072). Its strategic position on high ground overlooking the river suggests it was carefully placed to monitor movement along this important waterway. Such clusters of ringforts often indicate areas of particular prosperity or strategic importance in early medieval Ireland, where multiple families or branches of a clan established their homesteads within sight of one another.
