Overview

History & significance

Trereen Dinas is a promontory fort located on the Cornish coast near Mousehole in Penzance, Cornwall. The site comprises a defended headland separated from the mainland by a substantial defensive ditch and bank system, a characteristic arrangement of Cornish Iron Age fortifications. The fort dates to the Iron Age period, likely constructed between the first millennium and the Roman period. The dramatic coastal setting provided natural defensive advantages on three sides, whilst the inland approach was secured by the artificial earthwork barrier, making it a strategically positioned settlement and refuge site typical of southwestern British Iron Age coastal communities.
