Next to the Salzach river and the Mozarteum University of Music and Arts lies a beautiful castle with gardens, built by an archbishop for his beloved courtesan. Watch out for the "Garden of Dwarfs" and the Garden of Roses. Inside, you find the marble stairs of Raffael Donner, and the world's most beautiful wedding hall, the Marble Hall. If you plan to marry there, reservations should be made at least a year in advance. Weddings in English are only held on Tuesday and Friday. If you don't speak German, you can't get married any other day!
