The city’s biggest stunner is Schloss Ambras. Archduke Ferdinand II acquired the castle in 1564, the year he became ruler of Tyrol, and transformed it from a fortress into a palace. He was the mastermind behind the Spanische Saal (Spanish Hall), a 43m-long banquet hall with a wooden inlaid ceiling and Tyrolean nobles gazing from the walls. Also note the grisaille (grey relief) around the courtyard and the sunken bathtub where his beloved Philippine used to bathe.
