Tromsø lies in Northern Norway. It is the largest urban area in Northern Norway and the third largest north of the Arctic Circle. Most of Tromsø, including the city centre, is located on the island of Tromsøya, 350 kilometres north of the Arctic Circle. Substantial parts of the urban area are also situated on the mainland to the east, and on parts of Kvaløya—a large island to the west. Tromsøya is connected to the mainland by the Tromsø Bridge and the Tromsøysund Tunnel, and to the island of Kvaløya by the Sandnessund Bridge. Tromsø Airport connects the city to many destinations in Europe. The city is warmer than most other places located on the same latitude, due to the warming effect of the Gulf Stream.
The city centre of Tromsø contains the highest number of old wooden houses in Northern Norway, the oldest house dating from 1789. The Arctic Cathedral, a modern church from 1965, is probably the most famous landmark in Tromsø. The city is a cultural centre for its region, with several festivals taking place in the summer.
