Summary

Small, multivallate, inland promontory fort located on the tip of a NE-facing spur sited at the confluence of the Afon Asen, Afon Cynin and a stream. Stream valleys steep, narrow and wooded c. 40m below fort. Very steep surrounding slopes to N, E and W, less to SSW where land rises along spur. Triangular shape, measuring c. 70m N-S by 25m behind inner rampart, with area 0.22ha. Natural steep slope defence on N, E and W with, formerly, three lines of defence cutting off the promontory on easily approachable SSW. Most of site within deciduous woodland and scrub, but outer rampart, c. 65m long ESE-WSW, lay mostly in pasture field and this part was removed in 1984, when it remained as a spread of stone and clay. Its W end remains in overgrown woodland. Middle and short inner rampart (c. 25m long) and ditches remain well-preserved in woodland. Wide gaps between all three ramparts; between outer and middle 25m, between middle and inner 8m. Ditches now shallow, but banks to 5m high above. Possible entrance in centre of outer rampart recorded by OS, but DAT suggest entrance through middle and inner rampart at W end of the ramparts and the steep slope. On 1st Ed. OS map (1889). Minimal investigations, undated.

Enclosing Works

Three lines of defence cutting off the promontory on easily approachable SSW. Most of site within deciduous woodland and scrub, but outer rampart, c. 65m long ESE-WSW, lay mostly in pasture field and this part was removed in 1984, when it remained as a spread of stone and clay. Its W end remains in overgrown woodland. Middle and short inner rampart (c. 25m long) and ditches remain well-preserved in woodland. Wide gaps between all three ramparts; between outer and middle 25m, between middle and inner 8m. Ditches now shallow, but banks to 5m high above.

Enclosed Area:
Area 1:   0.22ha.
Total:   0.22ha.

Total Footprint Area:  Noneha.
