Hamburg's historic label, ‘The gateway to the world’, might be a bold claim, but Germany’s second-largest city and biggest port has never been shy. A leading light in the Hanseatic League in the Middle Ages, Hamburg became a centre of international trade, a legacy that continues today: it remains one of Germany's wealthiest cities and Hamburg’s maritime spirit still infuses the entire city. It's the sort of city where echoes of the city's port and history are everywhere, from the incessant cry of gulls overhead to the vibrant neighbourhoods awash with multicultural eateries, seaward-facing architecture and the gloriously seedy Reeperbahn red-light district.
