Overview

History & significance

Caswell Cliff Fort is a prehistoric promontory fort located on the Gower Peninsula in Swansea, Wales. The site occupies a naturally defended coastal position and comprises an Iron Age defensive structure, likely dating to the first millennium before Christ. The fort's defences exploit the dramatic cliff-edge topography, with evidence of ramparts and ditches constructed across the promontory neck to create a stronghold. Such coastal forts served as territorial markers, refuges, and centres of economic or military control during the Iron Age period.
