Black Head is the site of an Iron Age promontory fort. There are two parallel ramparts, up to 5.2 metres (17 ft) high, with ditches of depth 2.1 metres (6 ft 11 in); slight remains are visible of a further rampart beyond. The fort is a scheduled monument. There are also the remains of a rifle range, built in the 1880s and modified in later years.[2]
A memorial stone for the Cornish writer A. L. Rowse is situated on Black Head. In retirement he lived in the nearby hamlet of Trenarren. The stone includes the inscription "This was the land of my content".
