Listen to a performance of the Wiener Sängerknaben (Vienna Boys’ Choir) in the Imperial Chapel and be dazzled by a selection of crowns, jewelry and other curios, including a unicorn’s horn, in the Schatzkammer (Treasury) Museum. The Silver Collection still contains many of the objects that were left to the Austrian Republic when the Habsburg monarchy ended in 1918. Watch a show in the ornate Winter Riding School to see an impressive equestrian performance.
