Cardiff Castle's history began with the first Roman fortress built in the 1st C. The Norman Conquest in the 11th C. brought impressive fortifications. In the 19th C. the apartments were extended for the 3rd Marquess of Bute by architect Wm. Burges and contain unique and spectacularly decorated interiors. The Castle is open 362 days a year providing guided tours, medieval banquets, military museums, gift shop and function rooms available for hire.
