Rupertsberg

Saint Bertha of Bingen was the mother of Rupert of Bingen. Her biography was written, and subsequently her cult popularized, by Hildegard of Bingen, who lived in the same region, about four hundred years later. Bertha and Rupert share a feast day on 15 May.

Bertha was a descendant of the dukes of Lorraine, and had considerable property along the rivers Rhine and Nahe. She married Robolaus, a pagan, who died when their son Rupert was three years old. Bertha then retired to today's Rupertsberg with her son and the priest Wigbert. She built a small church and led a secluded life with much vigilance and fasting, gave the needy some of her wealth and gradually gathered other people to follow her example.
