This photo is from my first visit to Hamburg, Germany and it's the Town Hall or "Rathaus" as it's known in German. You can get there by taking the U3 that will drop you right next to the building. The metro station of the same name is "Rathaus" and it's very easy to get to. Impressive, don't you think? You can visit during day and you'll see some of the rooms of the building, but if your German is not very good, you will not be able to understand most of the explanations and history. Yet the building speaks for itself. Do not hesitate to visit.
