St. Sebaldus is a cool church with a cool history. The towers remained standing through the devastating bombings of WWII. There are photos throughout the church showing the ruins of everything around and the rebuilding.
We somehow missed the tower visit area but saw the people on top of a tower while we were up on the castle looking down over the city. The view from the Sebaldus towers must be amazing. and especially of the Weinachtsmarkt!
Definitely worth checking out!
