Economic muscle and cultural monument: the Mannheim harbour.
Large container ships, impressive loading facilities and huge container warehouses. It's no surprise to find such things in Mannheim, which happens to be home to the second largest inland port in Germany. The harbour area between the Rhine and the Neckar can be experienced either from the shore or, even better, from the water on a harbour cruise.
Top tip: It's impossible to get closer to the water without being in it. In the bar in Speicher7 you can enjoy fancy drinks, delicious tapas and an unbeatable view of the Rhine and Mannheim's famous harbour. This former emergency granary is today one of the hippest addresses in the city.
