Beaumaris Castle is part of CADW. Built under Edward I, as a few other castles in north Wales, including Chirk Castle, that we’ve visited this year. The story behind constructing the castle is impressive and the castle itself is beautiful.
But then we’ve discovered there were tunnels in the walls, going all the way around the castle. With a lot of rooms for defense. I was impressed by the organization that must have been in place back then, with all those little rooms.
