Crowned monogram of Olav V (V inside O).

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. The demi-lion on top of the crown was used by Norwegian governmental authorities from 1905, but was often omitted from about the year 1920, and officially omitted in the Royal Decree on the "arms of the realm" from March 19th, 1937.
