 In 1346, together with the castle of Burg Scharfenstein, a property of the Staufer, it was destroyed by armed men from Freiburg, and shortly afterwards flooded, from which disasters it never recovered, and was abandoned.The monastery in turn suffered an economic decline in the latter half of the 14th century, apparently during the time of abbot Paul I (1435-1455).In 1525 St. Trudpert's was plundered during the German Peasants' War.
