Royal ArmoryTucked under the Royal Palace, Sweden’s oldest museum is one of the city’s lesser-known gems, housing a wealth of royal paraphernalia. Opera fans will be particularly fascinated by the clothes that King Gustav III was wearing when he was murdered at a masked ball in 1792—the assassination that inspired Verdi’s Un Ballo in Maschera.
