Part destroyed, hillslope fort located on steep NE-facing slope of Allt Ddu S of Llanfaes church. Slope levels to N but to S overlooked by steeply rising moorland. Measures c. 100m E-W by 60m, with internal area c. 0.58ha. Defined by earth and stone bank and ditch, with outer face to 4m at SW corner, forming an incomplete oval with shorter and less high bank within it standing to 2.2m above ditch. Counterscarp to outer ditch on W. The slighter earthworks now ploughed away but completed the circuit on the N. No entrance defined but possibly from N. SE gap through outer rampart probably modern. Streams affect ditch. Rough upland grass. Trees and scrub on banks. Minimal investigations, undated.
