Crown of Frederick I
The Crown of Frederick I (German: Krone von Friedrich I.), was made by the Court Jewellers for Frederick I of Prussia in 1701, who crowned himself and his wife Sophie Charlotte in a baroque ceremony at Königsberg Castle, Königsberg. The crown was also used for the coronation of Frederick William I and his son, Frederick II (better known as Frederick the Great). He was a very frugal monarch, and although the crown was present at his coronation, he did not wear it.
