Imperial Treasury, Art museum and imperial collection at Hofburg Palace, Vienna, Austria

The Imperial Treasury houses an extensive royal collection inside the Hofburg complex, displaying crown jewels, ceremonial garments, and sacred objects. The museum consists of 21 exhibition rooms featuring gemstones, carved vessels, and religious relics gathered over many centuries.

The regalia arrived in Vienna from Nuremberg in the year 1800 as a safeguard against advancing French armies. After the dissolution of the Holy Roman Empire, the objects remained in the Austrian capital and were later opened to public viewing.

The name Schatzkammer refers to the Habsburgs' treasure chamber, split since Maria Theresa's day into a secular and an ecclesiastical section. The ecclesiastical rooms hold Baroque altars and devotional images, while the secular rooms display the coronation vestments of the Order of Saint Stephen and the Military Order of Maria Theresa. The wrought-iron entrance door still bears the monogram of Emperor Charles VI.

The entrance sits in the Schweizerhof courtyard, and combination tickets allow entry to multiple imperial collections. The rooms follow a manageable layout, making the visit accessible even for less mobile guests.

The narwhal tooth and the agate bowl were the two "inalienable heirlooms of the House of Austria"; Ferdinand I's three sons agreed that neither could be owned by one of them alone. The tooth was long taken for a unicorn horn, the Late Antique bowl for the Holy Grail.
