Complex promontory fort located on Griffin's Point headland promontory projecting W into Atlantic N of Watergate Bay. On S cliffs high, exposed, and precipitous. Stream valley almost surrounds landward E side. Steep descent to landward NE side. Encloses 0.7ha. Multiple ramparts and external ditches, slight works, two only terraces formed by scarping. Two ramparts visible, outer merging with natural slope before cliff top on N. Concentric on NE, but diverge towards S some 15m apart. Between these slight counterscarp thrown up in digging out inner ditch, with linear hollow outside associated with formation of outer rampart. To NE, further rampart and ditch extend downslope from outer concentric rampart to natural rock outcrop above the stream. W of this, outer concentric rampart and counterscarp within merge together, these then merging into the natural slope (inner rampart continues to cliff edge on NW). Ramparts c. 5m wide and c. 3.5m high outside and 0.9m within. Towards N, largely formed by cutting into the natural slope. External ditches 3m-5m wide, mostly visible as slightly concave shelves, or depressions up to 0.3m deep, but to 1.5m deep in places, notably on a 25m long section of inner ditch N of entrance, towards S. Entrance gap on SE towards cliff edge passing through inner earthwork, running across ditch on causeway 3m wide. Interior level area inside entrance. Beyond, moderate slopes to cliffs on N and W. Possible quarry pits or hut sites. Platform N of entrance, with slight bank 2m wide around W side, possibly remains of front wall. Possible outwork protecting entrance and possible early rampart on S 2m-3m from cliff edge. Variety of construction suggests unfinished or phased. Bronze Age barrow. Good condition under coastal grassland, although some ground lost to the sea, particularly to the S where cliffs high, exposed, and precipitous. Undated. On 1st Ed. OS map (1881).

Landward NE side multiple ramparts with external ditches. Two ramparts visible, outer merging with natural slope before cliff top on N. Concentric on the NE, but diverge towards the S some 15m apart. Between these is slight counterscarp thrown up in digging out inner ditch, with linear hollow outside associated with formation of outer rampart. To NE, further rampart and ditch extend downslope from outer concentric rampart to natural rock outcrop above the stream. W of this, outer concentric rampart and counterscarp within merge together, these then merge into the natural slope (the inner rampart continues to the cliff edge on the NW). Ramparts c. 5m wide and c. 3.5m high outside and 0.9m within. Towards N, largely formed by cutting into the natural slope. External ditches 3m-5m wide, mostly visible as slightly concave shelves, or depressions up to 0.3m deep, but to 1.5m deep in places, notably on a 25m long section of the inner ditch N of entrance, towards the S. This variety suggests possibly unfinished or phased.
