This earthwork defence, located just east of an old church site, graveyard and tower house, consists of a circular earthen bank that once protected a slightly concave interior space. Though time and human activity have taken their toll on the structure, the surviving western section of the bank still rises to an impressive 1.62 metres on its external face, with a substantial width of around 5 metres.

The ringwork has suffered considerable damage over the centuries, particularly on its eastern side where the earthwork has been completely destroyed. The southeastern sector has fared little better, having been used as a dumping ground for building materials, concrete and stones in more recent times. The western bank appears unusually broad, though this is partly due to erosion causing material to slip down into the interior of the fortification. Despite careful examination of the site, archaeologists have found no clear evidence of an original entrance or an external defensive ditch, or fosse, which would typically accompany such fortifications.

This type of earthwork castle represents an early form of Norman fortification in Ireland, typically dating from the late 12th to early 13th centuries. Ringworks were often quickly constructed defensive positions that could later be upgraded with timber palisades or stone walls. The proximity of this example to both a church site and a later tower house suggests this location held strategic importance over several centuries, with different generations adapting the site to their defensive needs.
