Winwaloe was a 5th and 6th-century religious leader and the first abbot of Landévennec Abbey in Armorica. Born around 460 to a prince of Dumnonia, he was educated by Budoc of Dol. After a dream discouraged his planned journey to Ireland, he established a monastery on the Île de Tibidy. Following three years there, he relocated his community to the opposite bank of the Landévennec estuary, where he eventually died in 532.
