Possibly a marsh fort located on a low knoll above the marshes around Afon Caradog to N, E and W, Anglesey. Site almost isolated by marsh, except on S. Fragmentary remains consist of two concentric lines of ramparts enclosing c. 183m by 201m except on NE side where three concentric ramparts. Internal area 3.7ha. On W line of outer rampart now a terrace with retaining wall, probably the original rampart facing. No ditches. This terrace incurves towards the road which now cuts through the fort NW-SE and possible entrance where incurves. Rescue excavations (no details) showed that on N side traces of earthworks were natural features, in the interior failed to reveal any structures. Only find from site was an unstratified bronze-iron terret of 'Don' type. Improved pasture. Much denuded by ploughing and banks fragmentary. On 1st Ed. OS map (1888). Undated.
