Tromsø Municipality is a municipality in Troms county, Norway. The administrative centre of the municipality is the city of Tromsø. Other notable settlements in the municipality include the villages of Bjerkaker, Ersfjordbotn, Jøvika, Kaldfjord, Kjosen, Kroken, Kvaløysletta, Lakselvbukt, Melvika, Movik, Oldervik, Sandneshamn, Sjursnes, Sommarøy, and Tromsdalen.
The municipality is the 21st largest by area out of the 357 municipalities in Norway. Tromsø is the 12th-most populous municipality in Norway with a population of 78,745. The municipality's population density is and its population has increased by 10% over the previous 10-year period. The city of Tromsø (within Tromsø Municipality) is the largest urban area in Northern Norway and the third largest north of the Arctic Circle anywhere in the world (following Murmansk and Norilsk). The center of the city of Tromsø is located on the island of Tromsøya, but the urban area also encompasses part of the nearby mainland and part of the island Kvaløya. Tromsø is north of the Arctic Circle. Tromsøya is connected to the mainland by the Tromsø Bridge and the Tromsøysund Tunnel, and to the island of Kvaløya by the Sandnessund Bridge.
The municipality is milder than most settlements on the same latitude, due to the effect of the westerlies reaching this far north, as well as the North Atlantic Drift, a branch of the Gulf Stream. Tromsø's latitude of just below 70°N renders annual midnight suns and polar nights depending on the season.
Tromsø contains the highest number of old wooden houses in Northern Norway, the oldest dating from 1789. Tromsø is a cultural hub for the region, with several festivals taking place in the summer. Due to its location, many countries had consulates or missions in Tromsø in the 1990s.
General information The city of Tromsø was established as an independent municipality on 1 January 1838 (see formannskapsdistrikt law). The city was completely surrounded by the Tromsøe landdistrikt (the rural municipality of Tromsø / later renamed Tromsøysund Municipality), but they were governed separately. As the city grew in size, areas were added to the city from the rural district.
On 1 January 1861, an area of Tromsøysund Municipality (population: 110) was transferred to the city of Tromsø. On 1 January 1873, an unpopulated area of Tromsøysund Municipality was transferred to the city. On 1 July 1915, another area of Tromsøysund Municipality (population: 512) was merged into the city of Tromsø. On 1 January 1955, the Bjerkaker area on Tromsøya (population: 1,583) was transferred from Tromsøysund Municipality to the city of Tromsø.
During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the city of Tromsø (population: 12,602), Tromsøysund Municipality (population: 16,727), most of Ullsfjord Municipality except for the Svendsby area (population: 2,019), and most of Hillesøy Municipality except for the parts on the island of Senja (population: 1,316) were all merged to form a new, larger Tromsø Municipality.
On 1 January 2020, the municipality became a part of the newly created Troms og Finnmark county, which replaced the old Troms county. On 1 January 2024, Troms og Finnmark county was divided and the municipality once again became part of Troms county.
Name
Coat of arms
The coat of arms (current version) was granted on 22 July 1983, although a variation of these arms has been in use since 1870. The official blazon is "Azure, a reindeer trippant argent" (). This means the arms have a blue field (background) and the charge is a reindeer. The reindeer has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. It is often surmounted by a mural crown with five or four turrets. The municipal authority currently uses a stylised rendering drawn by Hallvard Trætteberg (1898–1987) and adopted by royal resolution on 24 September 1941. The idea for a coat of arms for Tromsø was presented by A. T. Kaltenborn in 1855 and the coat of arms was first used in connection with the Industry and Crafts Exhibition in Tromsø in 1870. Over time, the background colour has been changed between blue and red. At one point it also used a natural landscape in the background. Although reindeer played little or no role in the city, Tromsø was the administrative center of the vast surrounding areas in the county were reindeer herding was common in this part of Northern Norway.
