The stunning Castell Coch in South Wales. It was originally a Norman castle but fell into disrepair. In the 1800s, the Marquess of Bute began to rebuild it, but the inside (and pointed roofs on the turrets) is more Victorian fantasy than accurate history!
The inside is incredible, with representations of the Greek Fates, creatures from Aesop's fables, and some pomegranates and raunchy monkeys amongst other things!
