Iron Age defended promontory. A massive bank and ditch forms the defences of this promontory fort. On the southern side a natural gully leading from the sea was enhanced and then extended to form a deep, semi-circular ditch protecting the promontory on the landward side. Material from the ditch was used to construct an earthen rampart, the inner face of which retained by a stone wall.


Excavation suggested that the first phase of the defences were constructed during the early Iron Age. No obvious trace of occupation was found associated with this phase of defence.
