With its spectacular coffered ceiling, Hamburg’s baroque Rathaus is one of Europe’s most opulent, and is renowned for its Emperor’s Hall and Great Hall. The 40-minute tours take in only a fraction of this beehive of 647 rooms. A good secret to know about is the inner courtyard, where you can take a break from exploring the Rathaus on comfy chairs with tables.
North of here, you can wander through the Alsterarkaden, the Renaissance-style arcades sheltering shops and cafes alongside a canal or 'fleet'.
