Oslo is consistently ranked one of the world's most expensive cities, yet Vigeland Park — one of the world's most visited sculpture parks — is completely free. The city also has more electric vehicles per capita than anywhere else on Earth.

Tromsø sits 350km north of the Arctic Circle, making it the northernmost city of its size in the world. In winter, the sun doesn't rise for two months (polar night); in summer, it doesn't set for two months (midnight sun).
