Introduction to Caernarfon Castle

Caernarfon Castle, nestled in the royal town of Caernarfon in North Wales, stands as one of the most magnificent and historically significant castles in the United Kingdom. A UNESCO World Heritage Site and a favourite among history buffs, photographers, and families alike, this fortress combines medieval grandeur with breathtaking surroundings. Whether you’re tracing the footsteps of Edward I, marvelling at polygonal towers, or soaking in views over the Menai Strait, Caernarfon Castle is a must-visit Welsh landmark.

Caernarfon Castle: History and Origins

Caernarfon Castle was commissioned by King Edward I of England in 1283 as part of his campaign to conquer Wales. The site had Roman roots and an earlier motte-and-bailey castle, but Edward’s vision was far grander. Inspired by the walls of Constantinople, the new design was intended to awe and subdue. Master architect James of St. George oversaw construction, which continued in phases until around 1330.

The castle’s walls incorporate bands of coloured stone and polygonal towers, including the iconic Eagle Tower. Its design symbolised power and domination over the newly conquered territory. In 1284, it became the birthplace of Edward II, the first English Prince of Wales – a tradition that continues today.
