“Salz” is the German word for “salt”.
Not surprisingly, Salzburg’s name and prosperity go back to the centuries-long international trade in, what else, but, salt.
Salt was so valuable that it was dubbed "white gold".
The income from the salt trade enabled the ruling prince-archbishops to build an affluent city.
Salzburg was also called the "Rome of the North" because of its Italian character and numerous churches.
