Roughly triangular univallate hillslope hillfort located just above Clatworthy Wood to N, S, W, on end of long W facing upland spur of Brendon Hills just above what is now Clatworthy Reservoir, but in prehistory would have been a deep upland valley at the headwaters of the River Tone. On 1st Ed OS map. Steep to precipitous slopes to N, S, W , moderate upslope to E. Main defence is earth and stone bank with ditch below. On N, SW and W bank is c. 3m wide and nearly 2m high, the ditch c. 1m deep and c. 2m wide. Ditch steep sided and rock cut. Quarry scoops to rear of bank on N and W sides. The examination of an animal scrape showed a stratum of iron pan 1.5m below the crest of the rampart, above this the bank being compact shale. Two possible entrances on the W and SE. Much affected by agriculture. Minimal investigations.

Main defence is earth and stone bank with ditch below. On N, SW and W bank is c. 3m wide and nearly 2m high, the ditch c. 1m deep and c. 2m wide. On S main defence appears to be sharp ditch, but much damaged here masks situation. Ditch steep sided and rock cut. The examination of an animal scrape showed a stratum of iron pan 1.5m below the crest of the rampart, above this the bank being compact shale.
