Castles in Wales

Rhuddlan Castle, begun in 1277 by Edward I, was the first of his Iron Ring fortresses. Its diamond plan, round towers, and river dock secured the Clwyd valley, symbolising English conquest. Today its haunting ruins stand as testament to ruthless ambition and the enduring imprint of medieval power on Welsh soil.

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.

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.

Conwy's majestic town walls are one of the finest examples of medieval defensive architecture in all of Wales. A visit to Conwy’s walls allows for a step back in time, offering a powerful reminder of the past while celebrating the resilience of a town that has grown and thrived within its ancient walls.

The Norman Conquest of 1066 unleashed a revolution in military architecture across Wales. Native timber and earthwork refuges yielded to enduring stone fortresses, concentric designs, towering keeps, layered defences, that anchored conquest and governance. Ludlow Castle emerged as the Marcher heart, witnessing royal tragedy and power plays that shaped border history for generations.

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.
