This square earthwork, measuring roughly 25.5 metres from northeast to southwest and 24.3 metres from northwest to southeast, represents a type of fortified settlement that was particularly common in Ireland during the 13th and 14th centuries. The site consists of a series of earthen banks and ditches; an inner bank along the southwestern side stands about half a metre high on its external face, whilst elsewhere the defences are marked by a scarp. Between these inner defences and an outer bank runs a flat-bottomed, water-filled fosse approximately 4 metres wide.

The outer bank, which would have provided an additional line of defence, remains visible along three sides of the site; the southwestern, northwestern, and northeastern edges. Standing 0.9 metres high on its inner face and 0.3 metres on the outer, this earthwork is about 4 metres wide. Unfortunately, the eastern corner and southeastern side have been lost to a later field boundary, leaving the defensive circuit incomplete. The interior of the site remains waterlogged, a condition that has likely persisted since medieval times given its proximity to the lough and the boggy nature of the surrounding landscape.

What makes this site particularly interesting is its relationship to a nearby crannog, an artificial island dwelling, located about 140 metres to the northwest in Cloonacleigha Lough. Connected to the shore by a causeway, this crannog would have been contemporary with or possibly earlier than the moated site, suggesting a complex pattern of settlement and defence in this area during the medieval period. Together, these monuments paint a picture of a landscape where security was paramount, and where natural wetlands were incorporated into defensive strategies.
