Today the place can still seem like the small English outpost Edward intended, with its elegant Georgian terrace along the front (designed by Joseph Hansom, of cab fame) and more plummy English accents than you’ll have heard for a while. Beaumaris Castle Beaumaris Castle might never have been built had Madog ap Llywelyn not captured Caernarfon in 1294. When asked to build the new castle, James of St George abandoned the Caernarfon design in favour of a concentric plan, developing it into a highly evolved symmetrical octagon. Sited on flat land at the edge of town, the castle is denied the domineering majesty of Caernarfon or Harlech, its low outer walls appearing almost welcoming until you begin to appreciate the concentric layout of the defences protected by massive towers, a moat linked to the sea and the Arab-influenced staggered entries through the two gatehouses. Despite more than thirty years’ work, the project was never quite finished, leaving the inner ward empty. You can explore a number of inner and outer wall walks, and wander through miles of internal passages in the walls.
