In Heraldry
The official crown of Norway has its official heraldic rendition. This design has been changed over the years and is most commonly recognised sitting atop the Coat of arms of Norway. However, many sections of government and especially the military are permitted to use the Crown of Norway on their shields. The use of the crown is heavily regulated and must always be displayed at the top of any page or other display.
