One day
Enter the old town through the Holstentor and cross to the market square for the Rathaus and the Niederegger marzipan house. See St Mary's Church and its fallen bells, climb St Petri's tower for the skyline, and visit the Buddenbrookhaus or Günter Grass house. Wander the hidden courtyards, then end with a boat trip around the island or a waterfront dinner.
