Though its earthen features have largely vanished from view at ground level, historical surveys reveal what was once an impressive rectangular enclosure measuring 56 metres from northwest to southeast and 45 metres from northeast to southwest. The site sits on low-lying land with a stream running along its northeastern edge, a strategic placement that would have provided both natural defence and a ready water supply.

The moated complex was defined by a sophisticated system of earthworks that created multiple lines of defence. Earthen banks stood at the northwestern and northeastern corners, whilst a fosse, or defensive ditch, ran along the southwestern, northeastern and southeastern sides. These inner defences were separated from additional outer banks positioned at the northwest and southeast, creating a layered defensive arrangement typical of medieval Irish fortifications. Such elaborate earthwork systems were commonly employed during the Anglo-Norman period and into the later medieval era, serving both defensive and status purposes for local lords.

At the eastern corner of this moated site stood a castle, now catalogued as monument RO045-171001. The combination of castle and moated enclosure suggests this was once a significant lordly residence, likely dating from the 13th or 14th century when such fortified sites proliferated across the Irish midlands. Whilst time and agriculture have obscured the physical remains that Gannon documented in 1972, the site remains an important piece of Roscommon’s medieval landscape, representing the complex military and social hierarchies that shaped medieval Ireland.
