Saint Wandrille, also known as Saint Wandregisel, was a Frankish courtier, monk, and abbot. He was born around 605 and educated at the Frankish court in Metz.
Saint Wandrille was part of a group of young courtiers who served Dagobert I. In 629, he retired from court to become a monk at Montfaucon under the guidance of Saint Balderic.
Saint Wandrille soon withdrew to live as a hermit in complete solitude at Saint-Ursanne in the Jura. He spent some time at the monastery of Saint Columban at Bobbio in northern Italy in 635. From there, he wished to travel to Ireland but got only as far as the abbey of Romainmôtier.
Saint Wandrille founded Fontenelle Abbey in Normandy. Fontenelle Abbey followed the rule of Saint Columbanus, and the abbey became an important center of learning. Saint Wandrille died on July 22, 668.
