Oslo, like many of its Scandinavian counterparts, is small and exorbitantly expensive – the most expensive, in fact. Which isn’t surprising considering Norway is oil rich on a level that has its per person GDP in the Qatar range. All it means is that if visitors want to check out the Scream by Edvard Munch in person or dig around their other remarkable arts and cultural hubs, they’d better remember to pack their wallets (with black cards).
