This former Summer residence was built from 1613 to 1616, by archbishop Marcus Sitticus, in an Italian villa style. The trompe-l'oeil virtuosity in the Music Room and Octagon, as well as garden fountains will surprise you more than you think (beware of the spray !). From caves to fountains, you then gain access to the Mechanical Theatre, where 113 figures come to life thanks to water power. There are zoological gardens with vast enclosures nearby.
