Carn Brea was occupied from 3,900BC, and was protected from attack by stone ramparts. Archaeological evidence shows the settlement was attacked and burned down at some point in its history. Hoards of Celtic coins have also been found on the hill during excavation.
According to folklore, a giant called John of Gaunt lived on this ancient site. The giant had a rivalry with another local giant called Bolster.
The two would often engage in battle and throw boulders at each other. The many large erratics found in this area are supposed to be remnants of their battles.
Directions: Carn Brea is to the South West of Redruth. A footpath from Churchtown leads up the hill.
