According to tradition, St. Trudpert's Abbey originated with Saint Trudpert, an Irish missionary and martyr in the southern Black Forest in the first half of the 7th century. He established a hermitage in Münstertal which became a monastery in the 9th century, and which by, at the latest, 900 had expanded to a monastic community supported by the influential noble family of the Liutfride. It is recorded that relics of Trudpert were translated to the abbey in 901 and shortly after 965.
