Housed in the oldest part of the Imperial Palace in Vienna, the Imperial Treasury is one of the most significant treasuries in the world. The collection shows of the decadence of the Austro-Hungarian Empire through its 1,000 years of treasures, as well as a variety of religiously significant relics. The highlight of the Secular Treasury is the behemoth imperial crown, a gemstone-embellished piece dating back to 962. Other items of note include a 2,680-carat Colombian emerald, one of the world’s largest sapphires, a golden rose, a narwhal’s tusk once mistaken for a unicorn horn and an ornate bowl which some believe to be the holy grail.
The Ecclesiastical Treasury, which often elicits a bit of skepticism in visitors, claims among its relics fragments of Jesus’s cross, a thorn from his crown and a swatch of the tablecloth used at the Last Supper.
The Imperial Treasury is closed on Tuesdays. Visitors up to the age of 19 enjoy free admission. Give yourself about 2 hours to visit the museum.
