Caernarfon Castle is a medieval fortress in north-west Wales run by CADW, the Welsh Government’s historic environment service and is a World Heritage site. Edward I had the current castle built in 1283, replacing the previous fortifications on the site. Unusually the towers of the castle are polygonal rather than round and we spent a lot of time walking up and down spiral staircases to take in fabulous views of Caernarfon and the castle itself.
