Castles in Wales

Caerphilly Castle, the largest in Wales, was raised by Gilbert de Clare in 1268–71 as a baronial masterpiece. Its concentric walls, four great towers, and vast artificial lakes created an island fortress of unparalleled strength. Today its haunting ruins and reflooded moats proclaim Marcher ambition and medieval engineering genius.

Castell y Bere may not be as famous as the imposing castles of Caernarfon or Conwy, but it holds a special place in the story of Wales.

Ewloe Castle provides a tangible connection to the momentous Welsh struggle for independence in the Middle Ages.

Beaumaris Castle stands as one of the last and greatest medieval castles built in Britain. Constructed by Edward I to consolidate his conquest of North Wales, its strategic location on Anglesey allowed the English to project power across the sea lanes.

Caernarfon Castle stands as a brutalist masterpiece of medieval military architecture. Built by Edward I to cement English rule in North Wales, its unique polygonal towers and banded masonry mirrored the walls of Constantinople. This formidable fortress remains a symbol of royal power and the traditional seat of the Prince of Wales.

Conwy Castle, begun in 1283 by Edward I, is one of Wales’ most complete Edwardian fortresses. Its eight great towers, concentric walls, and town defences secured the Conwy valley after Llywelyn’s fall. Today this UNESCO World Heritage Site remains a breathtaking symbol of medieval conquest and architectural genius.
