Hofburg and the Spanish Riding School, Vienna

The Hofburg was the Habsburgs' winter palace for more than 600 years, now home to the Austrian president and several museums: the Imperial Apartments, the Sisi Museum and the Silver Collection. The Imperial Treasury holds the crown of the Holy Roman Empire.

At the Spanish Riding School, white Lipizzaner horses perform classical dressage in a baroque hall; book performances well ahead, or watch the cheaper morning training. Also see the State Hall of the Austrian National Library, one of the most beautiful libraries in the world.
