This morning we toured Passau. Our guide is a high school teacher. We passed by a gymnasium ( high school) and learned about education in Germany. It is paid for by tax on corporations. The baroque church housed the world largest pipe organ. There was a concert at noon but we opted to skip it. We heard later that it was loud and complicated. We passed by the prince archbishop’s palace and back to the boat. There we saw a demo on how to make Apfel Streudel and a lecture all about Mozart. In the afternoon we departed on our river cruise to Linz traveling through three locks. We arrived in Linz just before sunset
