Promontory Fort at Sheep Island is a prehistoric coastal defence work located in Pembrokeshire, Wales. The fort occupies a naturally defensible headland position and exemplifies the promontory fort type, whereby a narrow neck of land connecting a coastal projection to the mainland was fortified with defensive earthworks to create an enclosed settlement area. Such sites are characteristic of later prehistoric Wales, typically dating to the Iron Age period, and served both defensive and settlement functions for communities exploiting coastal and maritime resources. The physical remains comprise the characteristic defensive bank or banks cut across the promontory, creating a barrier to restrict access to the enclosed coastal area.
