Promontory fort sited on rocky coastal headland of Chynhalls Point separating Coverack Bay to NE and Porthbeer Bay to SW. Irregularly-shaped, defined by steep sea cliffs on all sides except landward NW where two earth and stone banks, with intermediate ditch, cross narrowest neck of headland enclosing 1.5ha. Outer bank deteriorates to the S to 1m high and inner, with partial stone revetment, up to 2.6m high. Original entrance probably at centre of ramparts. Linear interior bank mapped by NMP. During WWII reinforced concrete pillbox manned by Home Guard erected at Chynhalls Point. Rocky gorse and heather interior. Coastal erosion. On 1st Ed. OS map (1879). Undated.
