Perched on the estuary of the River Seiont, Caernarfon Castle or Castell Caernarfon is steeped in royal history, built by Edward I as part of a series of castles designed to subdue and withstand assault from Welsh Princes. Its grand King’s Gate, polygonal towers, eagle statues and multi-coloured masonry hark to the architectural brilliance of Master James of Saint George, appointed by the King himself. Other castles he designed include those in Conwy, Harlech and Beaumaris on Anglesey. While there have been earlier versions of Caernarfon Castle, the stone fortifications that stand today were constructed in 1282.
