Caerphilly Castle is a substantial masonry fortress built from 1268 onwards by Gilbert de Clare, the Norman lord of Glamorgan, and represents one of the finest examples of concentric castle design in Britain. The castle comprises an inner ward surrounded by a powerful outer curtain wall, both enclosed within a formidable water defence system created by damming the Nant-y-Gledyr stream, making it one of the earliest and largest castles to employ such extensive hydraulic fortifications. The massive gatehouse structures, particularly the East Gatehouse with its projecting towers, exemplify the military architecture of the late thirteenth century and demonstrate the sophisticated engineering capabilities of the period. Following damage during the English Civil War, the castle underwent significant restoration in the early twentieth century, preserving this remarkable monument that dominated the lordship of Glamorgan for centuries after its construction.
