Multiple enclosure fort sited on a SW-facing ridge-top spur, above a sharp bend of the Eastern Cleddau. Steep surrounding slopes to N and W, moderate to E and S. Castell Gwyn II (Atlas No. 2101) nearby to WSW. Site overall c. 140m - 150m across, with interior bivallate enclosure c. 55m NNW-SSE by 30m internally, set within horseshoe-shaped outer enclosure. N straight side falls c. 50m below scarp edge to wooded valley below forming natural defence. Inner enclosure defined by two ploughed banks and ditches on its S side, with only one bank and ditch around entire circuit. Simple SW entrance. Rampart of outer horseshoe-shaped enclosure close to S side of inner enclosure, forming, in effect, a multivallate enclosuree for the entire site, but elsewhere it diverges. On W of this outer circuit bank best and to 2m high above ditch bottom, with good counterscarp. On E side defences overlain and affected by hedge-line. Also with simple SW entrance. Possibly phased construction but undated. Under improved pasture apart from hedge on E. On 1st Ed. OS map (1889).
