 After more than four centuries of economic and political decline, Michael Eggendorfer, the last abbot of the monastery, initiated the last renovations in 1521/22.During the Reformation in Switzerland, the abbey was abolished, and the Cathedral became the second main city church in 1524.The first extensions of the abbey included the east wing of the convent building with the chapter house of the monks on the ground floor, and a dormitory with latrines upstairs.
