Only now is Caerphilly's true stature becoming widely recognised. The world is waking up to the presence of this massive "Sleeping Giant" of a castle. It's location is totally unexpected. Surrounded by shops, offices and houses, it effortlessly dominates the town of Caerphilly. The fortress sprawls over 30 acres, making it easily the biggest castle in Wales and, along with Windsor and Dover, the largest in Britain.
The castle was built in the late 13th century by the Anglo-Norman lord, Gilbert de Clare to consolidate his grip on the lands he had captured. The fortress impressed onlookers right from the start, an awe struck Welsh poet describing it as "giant Caerffili". De Clare's castle, a high point in medieval military architecture, is a supreme example of the concentric "walls within walls" system of defence.
