This is another one of Wiesbaden's fountains - the Faulbrunnen. Claudia, who left me a comment, had suggested to take this picture. She told me that she used to get a can of water for her grandmother here regularly. Unfortunately, the area around it seems to be construction area at the moment (there's a fence and machinery standing around). I'll check back to see if something changes.
An also interesting discovery was the facade of the building behind it. It's an office building of a bank. The glass has a light blue tint (one of their corporate colors) which made the sky look really nice blue. I'll have to go back and see if I can get some more interesting photos out of that...
