Mentioned by Craig Weatherhill, in “Cornovia: Ancient Sites of Cornwall & Scilly” (Cornwall Books – 1985, revised 1997 & 2000. “This Iron Age fort, situated on a spur overlooking a deep valley to the north, was badly damaged by agriculture during the Second World War. Only its south-west half remains intact. Two concentric banks and ditches describe a circle 145m in overall diameter, with an entrance on the south-west. The north-eastern halves of these defences have been ploughed into a single spread bank 1.7m high. In contrast, the western ramparts reach a height of 4.3m. The west side of the fort is additionally defended by a third rampart and heavily counterscarped ditch which bulges out to form an annexe on the south-east, through which passes the entrance. 250m to the south, across the flattish neck of the hill spur, is an outwork formed by a single bank up to 2.8m high and a deep outer ditch. This terminates at the head of the steep slope on the east side, but on the west it returns in the direction of the fort.”
