Llandaff Cathedral stands on one of the oldest Christian sites in Britain. In the sixth century St Dyfrig founded a community close to the ford where the Roman road crossed the river Taff. He was succeeded by St Teilo and then Teilo's nephew, St Euddogwy. These three Celtic Saints remain patron saints of the present Cathedral and are represented by the three mitres in the Cathedral badge. Nothing remains of the original church but a Celtic Cross that stood nearby can still be seen near the door of the Chapter House.
