The highlight of the day was finding this synagogue off one of the back streets of Zell. We found a German Jewish man inside who spoke no English, but who was glad to show us English literature about history of the place. There was a Torah behind glass. The Jews in the area had been taken away during WWII, but a Christian bought and kept the place for the Jews to someday use it as a synagogue again.
We drove home from Zell and stopped at an overlook with a hiking path. We hiked to the Marienberg former Monastery along the rim of the river. On the way we saw this cemetery for German soldiers from WWII. I estimated the hike would be about 2 km. From signs we later saw, it ended up being 4.5 km there AND back. It took us longer than we expected, but it was a beautiful walk to remember.
