Built for Edward I, by Master James of St George, Conwy Castle is amongst the finest surviving medieval fortifications in Britain. It is, in a word, exceptional. You can’t fault it, from the grandeur of its high towers and curtain walls to its excellent state of preservation.
An estimated £15,000 was spent building the castle, the largest sum Edward spent in such a short time on any of his Welsh castles between 1277 and 1307.
