Caerphilly Castle is one of the most spectacular moat-bound castles in the world. The castle is the third largest in Europe and the second in the United Kingdom behind Windsor Castle. Building began in 1268 under the orders of Gilbert de Clare, although it took many decades to become the powerful building seen today. It is also famous for having introduced concentric castle defences to the shores of Britain. Caerphilly Castle is under the care of Cadw, a Welsh government funded organisation that conserves and maintains precious historical buildings in Wales. Having lived and worked near the castle for most of my life, I have had many opportunities to photograph this wonderful example of Norman architecture.
