The foundation of the collection, which was first documented in 1482, was the foundation of Isny ​​pastor Konrad Brenberg. The three-foot-high stairs are filled to the ceiling with book volumes. The collection includes writings by Martin Luther, Philipp Melanchthon and Ulrich Zwingli as well as valuable manuscripts and reprints from the time after the invention of book printing (1450 to 1500). -Preacher’s library
