Saint Gwenhael was a 6th-century Breton monk and missionary who served as the second abbot of Landévennec Abbey. Following the death of the monastery's founder, Winwaloe, in 532, Gwenhael was chosen to lead the community. He eventually resigned his position to travel through the Channel Islands and Ireland, where he studied the monastic traditions of Columbanus. During his travels, he worked to restore religious fervor and established numerous monasteries across several regions.
Life and mission
After training under Winwaloe, Gwenhael spent over three decades in Ireland. Upon returning to Armorica, he founded several monasteries, including sites in Cornwall and near the Blavet river. He was known for his holiness, with traditions suggesting that even wild animals sought shelter with him. He spent his final years in solitude, preparing for death according to local customs.
Veneration and legacy
His relics were once kept in Vannes before being moved to Paris and Corbeil to protect them from invaders. His influence remains visible in western Brittany through various dedications, including the church in Ergué-Gabéric and several parish churches. His name is also preserved in numerous local place names and surnames throughout the region.
