Commanding, oblong contour hillfort located at S end of Hatterall Hill, above confluence of Rivers Honddu and Monnow, and with Crug Hywel and Twyn y Gaer, guarding the S end of three of the four ridges of the Black Mountains. N, E Precipitous surrounding slopes to N and E, steep to W and moderate to strong to S. Measures c. 140m by 70m, with internal area of 3.28ha. Two periods. with precipitous natural slope defending E side. On S side series of scarps. Inner is c.2.2m high. Further S is berm of c. 18m, before another scarp 1.5m high, the latter continuing on S side, ending at E end. Outside this scarp is further berm of c. 6m followed by further scarp 1.2m high, and here berm is faint ditch in places. Further ditch outside this scarp, c. 2-3m wide with low bank of 0.7m high stopping short of S end. On W side bank to 3m exterior with farm track immediately outside it for most of length to its S end where bank lower to 1.5m on outside. Outside it there is a further scarp 1.8m high. To S, the ENE-WSW cross-bank to 2m high, with ditch, 1.5m wide and 1m deep, divides the enclosure into two parts. A track cross the middle of the bank. At N end of site massive bank, c. 2.5m high on S side and 3m high on N, with external ditch to 2m wide and 1.5m deep. Towards W end gap c. 1m wide and 1.2m deep. The bank is lower towards W end. Thus, possible two period phased construction, the first being univallate of 1ha to N, followed by multivallate. Oblique, elaborate, entrance with gateway flanked by bank 1.2m high to E and with knoll, c. 4m high on W, likely originally platforms or towers. The Offa's Dyke Long Distance Path enters the fort here. Multivallate S defences now rather worn. Area of hollows in S interior. It is possible that cross-bank may be post Roman. On 1st Ed. OS map (1881). Minimal investigations, undated.
