Cardiff Castle, Wales
Welcome to the beautiful, rustic ruins of Cardiff castle (or in Welsh Gaelic, Caerdydd Castell). An 11th century fortification most likely commissioned by William the Conqueror, it was built on top of a 3rd century Roman fort, as the site provides a good vantage point to defend the city. It was repeatedly involved in conflicts between the Normans and the Welsh before finally becoming little more than a decoration after a rich Marquess built a Victorian mansion and demolished all other medieval buildings minus this keep. Still, it makes a pretty awesome ruin!
