Germany's only urban rack-railway. It uses modern cars like the light railway and offers a nice view. Connecting Marienplatz with Degerloch
Small gallery with little stores (somewhat similar to Milan's famous gallery but a lot smaller). Right next to it is a building whose exterior is covered with plants.
