The root of the key of the metropolis of Cardiff is subject to much equivocalness. Cardiff is the anglicized adaptation of the Welsh make of “Caerdydd”. “Caerdydd” is divided into 2 words; “Caer”meaning ‘fort, and “Dydd” or “Diff”, which is thought by some to refer to the river Taff on which the castle of Cardiff stands. Others, however, take it to refer to the Roman general Didius, who was governor of nearby provinces. Although it is Europe’s youngest capital, having only been made the Welsh capital in 1955, the earliest evidence of habitation in Cardiff can be traced all the way back to 600BC, with the European Celts, but it was in AD 75, when the Romans came and built a fort in Cardiff that it became renowned. The relics of a Roman wall can still be found beneath Cardiff Castle. Cardiff was attacked in AD 850 by the Vikings followed by a Norman takeover in the 12th century, and it was the Normans who built the Cardiff Castle, on the same site as the Roman fort.
