Time and again, Gemany’s neighbours to the north in Denmark win the title of “the happiest people in the world”. But they are also richly endowed with the green lands between the North Sea and the Baltic. In Copenhagen, the capital city, you can try to track down the reason for their happiness. Once you arrive, you will see that Copenhagen is extremely flat; there is no projection that looms over the city. It is built on several small islands that have been artificially linked together. For a good view of the city and Øresund, go to the observation deck of the tower of City Hall.
