The Thirty Years' War caused much distress in the southwest of Germany. In 1632 the canons had to flee from the Swedes. The buildings survived the war, but in a very dilapidated state. It was left to the 15th abbot, the young Nikolaus Magnus Wierith, to undertake the restorations. Planning for the construction of the new church began in 1674; the first stone was laid in 1686, and the dedication took place in 1701. During this period the monk Isfrid Kayser (1712-1771) became known for his compositions.
