Nuremberg lies on a river called Pegnitz and on the Rhine–Main–Danube Canal. If you ever ever take a river cruise from the Netherlands down to Hungary (like my friend Ted Byrne did last summer), you’ll pass through Nuremberg.
This is not the canal, this is the river Pegnitz. Nuremberg has lots of nice places along the river and quite a few bridges. Like in Paris, London or Budpest (and contrary to Vienna) the river runs right through the city’s historic center.
