B. M.

Nice views with aesthetic skyscrapers.

Paulskirche - One of the cradles of democracy, it has a big meaning for the German history, and the transition from monarchy to democracy, as it was one of the first parliaments in Germany. If you're a history enthusiast, this place should be interesting for you, otherwise it won't be a special place to visit, as many more unique churches already exist in Frankfurt.

Consider going there when it's open, it's more interesting if you enter the church.
