Orb and the Royal Sceptre. Hessen Most of the crown jewels were stolen and destroyed by US army officers after the end of World War II. See Schlosshotel Kronberg. Saxony The Treasures and Crown Jewels of the Kings of Saxony are kept in Dresden. Prussia The crown and the insignia of the Kingdom of Prussia are kept at Hohenzollern Castle in Sigmaringen, Baden-Württemberg. Württemberg The treasures of the Kings of Württemberg are kept in the Württemberg State Museum in Stuttgart. Holy Roman Empire The Imperial Regalia like the Holy Crown of Charlemagne, the orb, the sceptre, the Holy Lance, and various other items are kept in the Schatzkammer Treasury in Vienna, Austria. Aside from those items already present in Vienna, the last Holy Roman Emperor, Francis II, brought there much of the Imperial regalia traditionally located elsewhere, before the final collapse of the Holy Roman Empire in 1806. Other objects associated with the coronation of Holy Roman Emperors can be found in Aachen, in the treasury of the Aachen Cathedral. The cathedral also houses a stone throne associated with Charlemagne, and was a traditional site for certain of the Imperial coronation ceremonies. The Aachen City Hall houses copies of several important items of the Imperial regalia, now in Vienna, which had previously been kept in their city. Both the old city hall and the core of the cathedral were once parts of the palace of Charlemagne.

It resembled the Imperial Crown of the Holy Roman Empire, although not intended as an exact copy. Its use as a national emblem was discontinued after the collapse of the German monarchy in November 1918; examples of the design can still be found on various buildings and monuments from that era, including the Reichstag. In practice, the crown jewels of the Kingdom of Prussia were used for the emperors of Germany, with some new items being created. Greece A set of crown jewels were created for the first modern Greek king, Otto of Greece, but he never wore them and took them with him after fleeing the country. His descendants later returned the regalia to Greece, but they were still never worn by any Greek monarch. Byzantine Empire In 1343,
