Oslo is a county and municipality, as well as the capital and largest city in Norway. Oslo was established as a municipality on 1 January 1838. Founded around 1048 by King Harald III "Hardraade" of Norway, the city was largely destroyed by fire in 1624. The Danish–Norwegian king Christian IV moved the city, rebuilding it closer to Akershus fortress, as Christiania (briefly also spelt Kristiania). In 1925, the city reclaimed its original Norwegian name, Oslo. The diocese of Oslo is one of the five original dioceses in Norway, which originated around the year 1070.

Tromsø is a city and municipality in Troms county, Norway. It is considered the northernmost city in the world and the most populous town north of it is Alta, Norway. It is also one of the best places to view the spectacular Northern Lights in winter. Tromsø is a surprise to most visitors: Here you find art, history, sophistication, good food and an infamous nightlife in a bustling, tiny city. All of it, though, is surrounded by spectacular scenery that is visible from everywhere in town. The city is home to the world's northernmost university, as well as research institutes and satellite based industry. The population is therefore highly skilled, but retains the straightforwardness and sense of humour that the North is known for.
