Castles in Wales

The imposing ruins of Dolbadarn Castle reveal much about its important strategic role in medieval times. At its heart stands the tall stone keep, which had three floors containing a great hall, private chambers, and battlements.

Caernarfon Castle, Edward I’s masterpiece of conquest, towers above the River Seiont, its banded walls and polygonal towers echoing Constantinople’s imperial grandeur. Built to crush Welsh resistance, it served as military bastion, seat of English law, and stage for royal pageantry—proclaiming unassailable dominion over Gwynedd for over seven centuries.

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.

Caernarfon Castle, Edward I’s imperial masterpiece begun in 1283, rises above the River Seiont with banded walls echoing Constantinople. Built to crush Welsh independence, it served as administrative capital and symbol of conquest. Today this UNESCO World Heritage Site remains one of the most visited and evocative castles in Wales.

North Wales has so many castles because it was fiercely contested ground. Its mountains and coastline demanded fortification, while Edward I’s conquest produced monumental strongholds such as Caernarfon and Conwy. These castles secured power, symbolised authority, and transformed the region’s landscape, economy and identity for centuries.
