The full story

How it was born, how it has changed and what it means.

The flag of Trondheim is red with a large yellow rose in the centre. It is a rarity in Norway: most municipalities in the country copy their coat of arms onto the flag, and Trondheim instead chose a flower the city has used since the Middle Ages.

How it came about

Trondheim has no modern coat of arms but an old seal, too complicated to put onto cloth. So when it wanted a flag it looked for another symbol: the rose of Trondheim, the official flower of the city.

The painter and teacher Arne E. Holm drew the version for the flag. The city council approved it in 1989, and a royal resolution confirmed it on 26 May of that year.

How it has changed

It has not changed since 1989. In 2020 Trondheim merged with the neighbouring municipality of Klæbu, and the symbols stayed the same.

What it means

The whole meaning is in the flower.

  • Rose: the symbol of the city since the Middle Ages, linked to Saint Olaf, the holy king buried in Nidaros Cathedral. It may recall the rose window, the great round window, of that cathedral, but it is not known for certain.

Fun facts

  1. A rose with an English accent

    Holm’s drawing is inspired by the Tudor rose, the emblem of the kings of England. Trondheim’s has eight petals, an even number that does not occur in real wild roses.

  2. The rose that threw out three heads

    In the 18th century the rose replaced three heads that appeared on the official seal of the city. Before that it was already used by the cathedral chapter, the citizens’ militia and guilds such as the bakers’ and the goldsmiths’.

  3. A flag for the millennium

    In 1997 the city celebrated its thousand years with a special flag, red with a yellow logo and the text ‘TRONDHEIM 997 - 1997’.

  4. Held up as an example

    Roman Mars, of the show ‘99% Invisible’, has cited it as an example of a well-designed city flag. Unlike that of Oslo, it carries no coat of arms or letters.
