Castell Caernarfon is recognised around the world as one of the greatest buildings of the Middle Ages. This fortress-palace on the banks of the River Seiont is grouped with Edward I’s other castles at Conwy, Beaumaris and Harlech as a World Heritage Site. But for sheer scale and architectural drama Caernarfon stands alone. Here Edward and his military architect Master James of St George erected a castle, town walls and a quay all at the same time. This gigantic building project eventually took 47 years and cost a staggering £25,000. The castle was born out of bitter war with Welsh princes. So of course its immense curtain walls and daunting King’s Gate were designed to withstand assault. But the polygonal towers, eagle statues and multi-coloured masonry sent a more subtle message.
