It was founded about 620 by Romaric, a lord at the court of Clotaire II, who, having been converted by Saint Ame, a monk of Luxeuil, took the habit at Luxeuil. It comprised a monastery of monks, among whose abbots were Saint Ame (570-625), Saint Romaric (580-653) and Saint Adelphus (d. 670), and a monastery of nuns, which numbered among its abbesses Saints Mactefelda (d. about 622), Claire (d. about 652) and Gébétrude (d. about 673).
