Sitting on a rocky crag above the Conwy river - this castle was also started in 1283 by Edward I and completed in 1289.

It was a key fortress in the “Iron Ring“ of castles built to contain the Welsh.

As with Caernarfon, Conwy is also a walled town, with walls some three quarters of a mile long and guarded by 22 towers.
