Bodø, Nordland (Norway)

Bodø had arms and flag approved 24 July 1959: A yellow sun on red. The designer was the grand old man of Norwegian heraldry, Hallvard Trætteberg. He took an element - the sun - from the arms Bodø had used since 1889 . These arms also included a boat on the sea in front of a range of mountains (really the profile of an island off the coast of the city). Bodø (in the county of Nordland) is the first Norwegian city north of the Arctic circle, and so the sun represents the midnight sun.

From 1. January 2005 the municipality of Skjerstad (number 1842), in the county of Nordland, was joined to the city of Bodø. Thus the symbols adopted by Skjerstad in 1990 and approved by Royal resolution dated 14. June 1991, a white millstone on a green field for the flag, became obsolete (the official Norwegian description was: "I grønt en hvit kvernstein").
