Coat of arms of Switzerland
The coat of arms of the Swiss Confederation shows the same white-on-red cross as the flag of Switzerland, but on a heraldic shield instead of the square field. The federal coat of arms (eidgenössisches Wappen) was defined by the Swiss Diet (Tagsatzung) in 1815, for the Restored Confederacy.
