Jacut was a 5th-century saint born in Wales to a royal family. As the son of Fragan, a prince of Dumnonia, he moved to Brittany with his parents to escape a plague in Cornwall. Raised in Ploufragan alongside his siblings, he eventually studied under Budoc of Dol on the Île Lavret. Throughout his adult life, he was active in the region, establishing several churches across Brittany.
Life and work
Following his relocation to Brittany, Jacut was educated on the Île Lavret. He spent his maturity building churches within the territory. He was part of a notable family of religious figures, including his brothers Winwaloe and Wethenoc, as well as his sister Creirwy.
Veneration and memory
His legacy is preserved through several locations, including the Abbey of Saint-Jacut and the towns of Saint-Jacut-de-la-Mer, Saint-Jacut-du-Mené, and Saint-Jacut-les-Pins. He is recognized in both Catholic and Orthodox traditions, with his feast day observed on February 8.
