This opulent summer home of the Hapsburgs is now one of Austria's top tourism sites. It was the site of Mozart's first public concert at 6. Emperor Franz Joseph was born here in 1830 and spent his last year here in 1916. After the war, it became the property of the new republic. It is now a UNESCO world heritage site and approximately 40 of the 1440 rooms are open to the public. The site includes extensive gardens to which a Japanese garden was added in 1998.
