Gobrien de Vannes was an eighth-century prelate from Armorica who served as the nineteenth Bishop of Vannes. Born around 660, he received his education at the monastery of Saint-Gildas de Rhuys before being ordained as a priest. During his seventeen-year tenure as bishop, he was known for his dedication to the community, particularly through his service to the sick and the impoverished. Later in life, he retired to a hermitage in Josselin, where he spent his final years.
Life and ministry

After completing his training, Gobrien served the people of the Vannes region as a priest and later as their bishop. He was recognized for his charitable works, providing care to those in need. Following his leadership in the diocese, he sought a more solitary life at the Josselin hermitage. He passed away in 725, leaving behind a legacy of service to the local church in Armorica.
Veneration and death
Following his death, Gobrien was laid to rest at the Saint-Servant chapel. He is remembered as a saint in the Catholic and Orthodox traditions, with his feast day observed on November 10. Local tradition includes accounts of his ability to perform healings, specifically through the use of rusted nails.
