Tudwal

Saint Tudwal (Tugdual) was a monk from Wales who went to Brittany and became Bishop of Tréguier. He reposed around 564 and founded a monastery at Lan Pabu.

Three places on the Lleyn Peninsula in Gwynedd recall his name, and his relics are still honoured at Tréguier. One of his disciples was Saint Briarch, who followed him from Wales to Brittany. The calendar commemorates him on 30 November, and sometimes also on 1 December (New Calendar), as a saint of the undivided Church.
