Tromsø is a city in Tromsø Municipality in Troms county, Norway. The city is the administrative centre of the municipality and the county. The city is located on the island of Tromsøya which sits in the Tromsøysundet strait, just off the mainland of Northern Norway. The mainland suburb of Tromsdalen is connected to the city centre on Tromsøya by the Tromsø Bridge and the Tromsøysund Tunnel. The suburb of Kvaløysletta on the island of Kvaløya is connected to the city centre by the Sandnessund Bridge.
The city centre 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.
The town has a population (2024) of 42,782 and a population density of .
In 2026, Tromsø holds the title of European Youth Capital, becoming the northernmost city to ever receive this designation. The year-long programme focuses on empowering young people in the Arctic region and fostering youth participation in local governance.
Names and etymology
The city of Tromsø is named after the island of Tromsøya, on which it stands. The last element of the city's name comes from "island" (, ), but the etymology of the first element is uncertain. Several theories exist. One theory holds "Troms-" is derived from the old (uncompounded) name of the island (Old Norse: Trums). Several islands and rivers in Norway have the name Tromsa, and the names of these are probably derived from the word straumr, which means "(strong) current". (The original form must then have been Strums, for the missing s, see Indo-European s-mobile.)
The Sámi name of the island, Romsa, is assumed to be a loan from Norse; in Sámi, word-initial consonant clusters are dispreferred. However, an alternative form with the consonant cluster, Tromsa, is in informal use. A theory holds that the Norwegian name of Tromsø derives from the Sámi name, though this theory lacks an explanation for the meaning of Romsa. A common misunderstanding is that Tromsø's Sámi name is Romssa with a double "s". This, however, is the accusative and genitive form of the noun used when, for example, writing "Tromsø Municipality" (Romssa suohkan). In Finnish, however, the word is written with a double "s": Tromssa.
History
The area has been inhabited since the end of the last ice age. Archeological excavations in Tønsvika, have turned up artefacts and remains of buildings estimated to be 9,000 to 10,000 years old.
Middle Ages: a fortress on the frontier
The area's rich Norse and Sámi heritage is well documented. The Norse chieftain Ohthere, who lived during the 890s, is assumed to have inhabited the southernmost reaches of today's Tromsø municipality. He described himself as living "furthest to the North of all Norwegians" with areas north of this being populated by Sámi. An Icelandic source (Rimbegla) from the 12th century also describes the fjord Malangen in the south of today's Tromsø municipality as a border between Norse and Sámi coastal settlements during that part of the Middle Ages. However, archaeological finds show that the Vikings have been present on the main island itself. In a burial/settlement near today's airport, a sword and other combat tools have been found, as well as household tools typical for the Norwegians. In addition, one of Northern Norway's largest Viking treasures is found on the island itself. There has also been extensive Sámi settlement on the coast south of this 'border' as well as scattered Norse settlements north of Malangen − for example, both Sámi and Norse Iron Age (0–1050 AD) remains have been found on southern Kvaløya.
The first church on the island of Tromsøya was erected in 1252. Ecclesia Sanctae Mariae de Trums juxta paganos ("The Church of Saint Mary in Troms near the Heathens" − the nominal "heathens" being the Sámi), was built during the reign of King Hákon Hákonarson. At the time, it was the northernmost church in the world. Around the same time a turf rampart was built to protect the area against raids from Karelia and Russia.
Tromsø was not just a Norwegian outpost in an area mainly populated by the Sámi, but also a frontier city towards Russia; the Novgorod state had the right to tax the Sámi along the coast to Lyngstuva and inland to the Skibotn River or possibly the Målselv River, whereas Norway was allowed to tax areas east to − and including − the Kola Peninsula. During the next five hundred years Norway's border with Russia and the limits of Norwegian settlement would be pushed eastwards to Sør-Varanger Municipality, making Tromsø lose its character as a "frontier town".
1700s and 1800s: the "Paris of the north" During the 17th century, while Denmark–Norway was solidifying its claim to the northern coast of Scandinavia, the redoubt Skansen was built. Despite only being home to around 80 people, Tromsø was issued its city charter on 20 June 1794 by King Christian VII. This coincided with, and was a direct consequence of, the abolition of the city of Bergen's centuries-old monopoly on the trade in cod. Tromsø quickly rose in importance. The Diocese of Hålogaland was created in 1804, with the first bishop being Mathias Bonsak Krogh. The city was established as a municipality 1 January 1838 (see formannskapsdistrikt law).
Arctic hunting, from Novaya Zemlya to Canada, started up around 1820. By 1850, Tromsø was the major centre of Arctic hunting, overtaking the former centre of Hammerfest. Tromsø had trading contacts with both Central Europe and Russia (specifically Arkhangelsk) during this time, the latter of which resulted in the development of the pidgin language Russenorsk.
In 1848, the teacher training college was also moved from Trondenes Municipality (near current-day Harstad) to Tromsø, with part of its mission being to educate Sámi scholars − there was a quota ensuring that Sámi gained access.Statsarkivet i Tromsø 1992: Arkivkatalog TROMSØ OFFENTLIGE LÆRERSKOLE, page 6. The teacher college was followed by the Tromsø Museum in 1872, and the Mack Brewery in 1877.
In the 19th century, Tromsø became known as the "Paris of the North". How this nickname came into being is uncertain, but the reason is generally assumed to be that people in Tromsø appeared far more sophisticated than visitors from the south typically expected.
Early 1900s: exploration and war
By the end of the 19th century, Tromsø had become a major Arctic trade centre from which many Arctic expeditions originated. Explorers like Roald Amundsen, Umberto Nobile and Fridtjof Nansen made use of the know-how in Tromsø on the conditions in the Arctic, and often recruited their crews in the city. The Northern lights observatory was founded in 1927.
When Germany invaded Norway in 1940, Tromsø served briefly as the seat of the Norwegian government. General Carl Gustav Fleischer arrived in Tromsø on 10 April 1940 after flying in terrible conditions from Vadsø. From Tromsø he issued orders for total civilian and military mobilisation and declared Northern Norway a theatre of war. Fleischer's strategic plan was to first wipe out the German forces at Narvik and then transfer his division to Nordland to meet a German advance from Trøndelag. The Germans eventually captured all of Norway, after allied support had been withdrawn, although they encountered fierce resistance from the Finnmark-based Alta Battalion at Narvik. Tromsø escaped the war unscathed, although the German battleship Tirpitz was sunk by RAF bombers during Operation Catechism off the Tromsøy island on 12 November 1944, killing close to 1,000 German sailors.617 Squadron - The Operational Record Book 1943 - 1945 http://www.dambusters.org with additional information by Tobin Jones; Binx Publishing, Pevensey House, Sheep Street, Bicester.

At the end of the war, the city received thousands of refugees from Finnmark county and the northern areas of Troms − areas which had been devastated by German forces using scorched earth tactics in expectation of a Red Army offensive.
Late 1900stoday: rapid expansion Expansion after World War II has been rapid. The rural Tromsøysund Municipality and Ullsfjord Municipality, and most of Hillesøy Municipality, were merged with Tromsø on 1 January 1964, creating today's Tromsø municipality and almost tripling Tromsø's population − from 12,430 to 32,664. In addition, the population growth has been strong, with at times more than 1,000 new Tromsøværinger (residents of Tromsø) annually. The population of Tromsø municipality today is 68,239, and the urban area, Norway's ninth most populous, is home to 58,486 people. This excludes most of the city's students, however, who often do not change their address when moving to Tromsø.
A major development was the opening of Tromsø Airport in 1964, situated on the main island, and in 1972 the University of Tromsø was opened, at the time one of four universities in Norway and the only one serving the northern half of the country. A local teacher's college and museum were eventually incorporated into the university. The Norwegian Polar Institute was moved to Tromsø from Oslo in 1998. More recently, the university has expanded further through two mergers, first with University College Tromsø in 2009 and then with University College Finnmark in 2013.
Geography Tromsø is the 12th largest municipality in Norway with a population of 78,745. The city is home to the world's northernmost university and also houses the northernmost botanical garden and planetarium.
The city centre is located on the east side of the Tromsøya island − over north of the Arctic Circle at . Suburban areas include Kroken, Tromsdalen (on the mainland, east of Tromsøya), the rest of the Tromsøya island, and the eastern part of the large Kvaløya, west of the Tromsøya island. The Tromsø Bridge and Tromsøysund Tunnel both cross the Tromsøysundet strait connecting the mainland with Tromsøya by road. On the western side of the city, the Sandnessund Bridge connects Tromsøya island with Kvaløya island.
The highest point in the municipality is the tall mountain Jiehkkevárri. There are also many other tall mountains within the municipality including Hamperokken, Store Blåmannen, Store Fornestinden, and Tromsdalstinden. The Lyngen Alps mountain range lies along the Tromsø-Lyngen municipal border. There are many islands within the municipality of Tromsø including Hillesøya, Kvaløya, Rebbenesøya, Ringvassøya, Store Sommarøya, and Tromsøya. There are also several fjords that are located in Tromsø including the Balsfjorden, Kaldfjorden, Malangen, and Ullsfjorden.
Climate
Tromsø experiences a subarctic climate (Köppen climate classification Dfc, Trewartha Eolo) as winter temperatures are just cold enough to qualify and the summer season is short. However, precipitation amount and pattern, with maximum precipitation in autumn and winter, as well as lack of permafrost, are atypical for subarctic areas and more typical for oceanic climates. Owing to the ice-free Norwegian Sea and the westerlies bringing the mild air ashore, winter temperatures in Tromsø are moderate and extremely mild for the latitude. Summers are rather cool, sometimes cloudy and rainy, and sometimes sunny, often with large variations from year to year and from month to month, giving a completely different experience, all depending on the weather pattern.
