For this audio guide tour, you will need an Android or iOS device and headphones. The history of Hamburg is closely linked with that of Denmark. Altona, now a district of Hamburg, was once the second-largest city in Denmark. Less well-known is the fact that St. Pauli, as we know it today, was shaped by many liberal influences from Denmark, and this extends beyond just sexual freedom.

This exciting tour begins at the St. Pauli Landungsbrücken with the old Elbe Tunnel. You will walk along the Elbe to what was once Denmark's and later Germany's largest fishing port, and then return through Hamburg's notorious entertainment and red-light district, St. Pauli, with its Reeperbahn. Enjoy your tour from Hamburg to Altona and back! Solve the small puzzles and photograph the solutions.
