The world's northernmost Protestant cathedral, built in 1861. With 800 seats, it's one of Norway's major wooden churches.
Tromsø Cathedral is a cathedral of the Church of Norway located in the city of Tromsø in Tromsø Municipality in Troms county, Norway. The cathedral is the church for the Tromsø Domkirkens parish. It is the headquarters for the Tromsø domprosti (arch-deanery) and the Diocese of Nord-Hålogaland. This cathedral is notable since it is the only Norwegian Protestant cathedral made of wood.

Nordnorsk Kunstmuseum
Has art from Northern Norway from 1800 onwards, and Norwegian art in general. Look out for their temporary exhibits.
Vår Frue Kirke
This tiny church is the seat of the world's northernmost Catholic bishop, and also dates from 1861.
Macks Ølbryggeri
Offers guided tours of the brewery. Claims to be the world's northmost brewery, but Svalbard Bryggeri in Longyearbyen is further north. Established in the city centre in 1877, the brewery is still owned by the same family. Monday to Thursday, they offer guided tours at 13:00 if there are at least four visitors. So you risk coming there for your tour, and not getting it. This brewery is looking for an alternative place to set up a new factory, seemingly in Nordkjosbotn (Balsfjord municipality), 70 km (45 mi) to the south. But the city council is striving to keep the brewery in or near Tromsø, insisting on their ties with another famous place in Tromsø, Ølhallen — see below: Drink – Bars and pubs. The debate and the population's relationship with Mack is getting so passionate that some threaten to boycott the brewery’s products if they leave the city.
Has temporary exhibits on the North. Their location in an 1838 building in the main street is superb, and there is free admission.
Polarmuseet i Tromsø
The museum is housed in an old warehouse from 1830 and displays Arctic hunting from Tromsø and expeditions to the Arctic. A guidebook is provided for English and other languages, though many of the displays are in Norwegian, so you'll need a translation app to read them such as Google Translate.
Tromsø Kunstforening
Has temporary exhibits of contemporary art.
