Felix of Rhuys was a 10th-century Benedictine monk and hermit from Brittany. Born into a wealthy family in Quimper around 970, he initially lived as a recluse on the island of Ushant. Following the Norman invasions, he sought refuge at Fleury Abbey. There, he was tasked by the Duke of Brittany and the Abbot of Fleury to rebuild the Saint-Gildas-de-Rhuys Abbey, which had been previously destroyed. He successfully led the reconstruction of the monastery using stone instead of wood.
