Caerphilly Castle was a vast medieval fortress built in hostile territory to secure control of the upland region of the cantref of Senghennydd. Its concentric layout represented the very latest in castle design and would be imitated by the later Royal castles built by Edward I to suppress North Wales. A must see when visiting Cardiff.
