At the end of the seventeenth century Emperor Leopold I commissioned the Baroque architect Johann Bernhard Fischer von Erlach, who had received his training in Rome, to design an imperial hunting lodge for his son, Crown Prince Joseph, later to become Emperor Joseph I. Replacing the château de plaisance built on this site for the dowager empress Eleonora of Gonzaga in 1642, it was to grow into a palatial imperial residence over the course of the eighteenth century.
