Concierge.com's insider take:
The area known as the Altstadt is centered on Rathausmarkt. Here, you can visit the 647-room Rathaus (Rathausmarkt; 49-40-428-312-470), one of the most interesting city halls in Germany, and the baroque Hauptkirche St. Michaelis (Englische Planke; 49-40-376-780), located just a few blocks west, which has sweeping views of the city and port from its elevator-accessible tower. Stroll down to the port, one of the busiest in the world, and take in Hamburg's oldest fish market, which dates back to 1703 and is teeming with locals and visitors alike.
