Saint Tudwal (died c. 564), was a Breton monk, considered to be one of the seven founder saints of Brittany. Tudwal is said to be a son of King Hoel (Breton: Hoel I Mawr), a late 5th- and early 6th-century member of the ruling dynasty of Cornouaille (Breton: Kernev). Tudwel is thought to have been brought up in Lydstep in Wales (Cymru). He then went to Ireland (Éire) for religious education later returning to Wales becoming a hermit on Saint Tudwal's Islands (Welsh: Ynysoedd Tudwal). Tudwal subsequently travelled to Brittany, settling in Lan Pabu with 72 followers, where he established a large monastery under the patronage of his cousin, King Deroch of Domnonée. Tudwal was later made Bishop of Treguier. In iconography, Tudwal is shown as a bishop holding a dragon, now the symbol of Trégor (Breton: Treger). Today 1st December is the feast day of Saint Tudwal.
