Menai Strait and Castell Coch

This week, Derek Brockway's walks are full of history and amazing building feats. First he's on the banks of the Menai Strait walking between two brilliant bridges, the Britannia Bridge and the Menai Suspension Bridge. His guides are local WI members, and it was on Anglesey that Britain's first ever WI meeting was held over 100 years ago. Later, Derek treks between two captivating castles, at Caerphilly and Castell Coch, and even gets a chance to dress up as a medieval knight.
