Overview

History & significance

Stack Rock Fort is a mid-nineteenth-century coastal defence fortification located on a rocky outcrop in the waters off Pembrokeshire, Wales. Built between 1850 and 1852 as part of the extensive programme of Victorian-era coastal fortifications, the fort was designed to defend against potential French naval incursions during a period of heightened international tension. The structure comprises a circular gun battery mounted upon the rocky stack, incorporating casemates and gun positions characteristic of mid-century military engineering. Following the decline of its strategic importance in the twentieth century, the fort was abandoned and has since become a distinctive monument to Victorian defence architecture and engineering ambition in Wales.
