Rathaus Stuttgart
Stuttgart's town hall has been called one of the ugliest in all of Germany. That may be true, but the sweeping interior houses a nice cafe, where you can have a coffee or cake in the afternoon. The true highlight, however, are the Paternoster lifts, constantly moving, doorless elevators that you hop on and off. These may be the most accessible lifts in Germany, and if you are interested in the concept (or just want to have a look), they are definitely worth the trouble. The experience is one of the most Insta-worthy experiences in Stuttgart.
