Overview

History & significance

Treryn Dinas is a promontory fort situated on the Cornish coast near Mousehole in the parish of Paul, Cornwall. The site occupies a naturally defended headland and comprises substantial defensive earthworks including a series of parallel banks and ditches that cut across the promontory to create multiple enclosures. The fort is believed to date to the Iron Age, representing a significant example of coastal defensive settlement from this period in south-west England. Its location on an exposed maritime promontory suggests it may have served strategic purposes related to both territorial control and maritime activity during the Iron Age occupation of Cornwall.
