Downtown Tromsø in spring

Tromsø is the eight-largest municipality in Norway with a population 63,596, and the centre of the ninth-largest urban area, with a population of 53,622.[2] The city is home to the world's northernmost university (the University of Tromsø), brewery, botanical garden[1] and planetarium.[10]

The city center is located on the east side of the Tromsøya — over 300 km inside the Arctic Circle at 69° 40' 33'' N, 18° 55' 10'' E. Suburban areas include Kroken, Tromsdalen (on the mainland, east of the Tromsøya island), the rest of the Tromsøya island, and the eastern part of the large Kvaløya, west of the Tromsøya Island. Tromsø Bridge and a four laned road tunnel connects the mainland with Tromsøya by road, and, on the western side of the city, Sandnessund Bridge connects Tromsøya island with Kvaløya island.
