Probably founded in the 6th century, either by Saint Daniel (died 584?) or by Saint David. Its history before the Conquest is obscure. The cathedral, the smallest in England or Wales, destroyed by the Normans in 1071, rebuilt by them, burned 1402, and again rebuilt in the 16th century, has served since the Reformation, as both an Anglican cathedral and parish church. The diocese consisted of Anglesea, Carnarvonshire, the greater part of Merionethshire, and some parishes in the counties of Denbigh and Montgomery. Included in the episcopal list are Anian (1267-1305), who baptized Edward II, and Thomas Skevington, or Pace (1509-1533), who completed the cathedral. The last Catholic bishop was William Glynn (1553-1558).
