The Imperial Treasury (German: Kaiserliche Schatzkammer) at the Hofburg Palace in Vienna, Austria contains a valuable collection of secular and ecclesiastical treasures covering over a thousand years of European history.
[1] The entrance to the treasury is at the Schweizerhof (Swiss Courtyard), the oldest part of the palace, which was rebuilt in the sixteenth century in the Renaissance style under Holy Roman Emperor Ferdinand I.
In the eighteenth century, Maria Theresa had the Habsburg treasures moved to its present location, covering up the fact that the dynasty's assets had been largely affected by the expensive wars against rivaling Prussia.
The Imperial Regalia arrived in the last days of the Holy Roman Empire around 1800 from Nuremberg, where they had been kept since 1424, in order to save them from the advancing French troops under Napoleon.
Part of the treasury are also the crown of the Transylvanian prince Stephen Bocskay and the two "inalienable heirlooms of the House of Austria": a giant narwhal tooth which was thought to be the horn of a unicorn (Ainkhürn) and the Agate bowl from Late Antiquity which was thought to be the legendary Holy Grail; furthermore the Napoleonica artifacts of Napoleon II and his mother Marie Louise.
The Court Office Director (Hofamtsdirektor) Wilhelm von Weckbecker, who was responsible for the treasuries, and treasurer Ulreich handed over to the Lord Chamberlain (Oberstkämmerer) Count Leopold Berchtold not only Empress Zita's private jewellery, but also the Habsburg-Lorraine family jewellery from display cases XII and XIII (Vitrine XIII) of the Secular Treasury.
