Archbishop Wolf-Dietrich von Raitenau had this palace built as a housing estate for his dearly loved wife Salome Alt. Since the bond to the bourgeois daughter was illegitimate and the wife and children were not allowed in the city. Wolf-Dietrich had this generous and pompous palace built in front of the doors of the then-city. A spacious baroque garden, the „Irrgarten“, a labyrinth made out of beech hedges and the dwarfs garden was meant to compromise for the social ostracism of the family. After a disastrous fire the palace was rebuilt. Due to that the redundancy of the palace is only rudimentary recognizable. The most popular structure that survived the flames are the Marble Stairs and the Marble Hall, is acknowledged to be one of the "most beautiful wedding halls in the world". Besides the civil registry office the palace accommodates the office of Salzburg's mayor and the municipal administration at this historical address.
