Yes this garden did feature in some scenes of the Sound of Music. Originally the Palace was called Altenau , built in 1606 by Prince Archbishop Wolf Dietrich for his mistress Salome and their 10 children. The marble staircase inside was built by Raphael Donner and leads up to the marble room, popular among those getting married. The landscaping and architecture reflects the wealth that was being created during the rule of the Prince-Archbishops (16-18thC). In the gardens is a small hut called the Zauberflotenhauschen where Mozart is said to have written the Magic Flute. Also check out the garden of Gnomes .
