Prince-Archbishop of Salzburg Count Leopold Anton Eleutherius von Firmian (1679-1744) commissioned the palace in 1736 on the shores of an existing pond after he had enriched himself in the process of expelling over 22,000 Protestants from Salzburg. He acquired the area between the palace and the Untersberg as a family estate, which he passed on in May 1744 to his nephew Count Laktanz Firmian, who used it to house his large collection of paintings. This included works of Titian, Dürer, Poussin, Rubens and Rembrandt.
