Copenhagen

Copenhagen, Denmark's capital, with a population of around 799,000 people. It is the most populated and metropolitan city in the country, despite its origins as a fishing village frequented by Vikings in the 10th century. The cost of living in Copenhagen is around $4,234 per month for a family of four (over 37,000 kroner).

That doesn't even take into account rental prices that are more expensive than 84 per cent of the rest of the globe and excessively high food expenses. Denmark is already renowned as one of the world's most costly and opulent countries, and this is its most expensive city.

A few of the short Copenhagen facts are that Hans Christian Anderson, the creator of classic stories like The Little Mermaid, is buried in the Assistens Kirkegård Cemetery in Nørrebro, Copenhagen. Everyone else in the world refers to that exact pastry kind as a "Danish." In Copenhagen, the Danish pastry is ironically referred to as "Viennese bread!" Everywhere else, it's Danish.
