The second stage of the Copenhagen Metro is nearing completion, but the city is still dotted with its construction sites. This one is situated at the end of the beautiful lakes that flow through Copenhagen. The company constructing the Metro have put a lot of effort into making the sites as nice looking as possible and have decorated the hoardings in all sort of creative ways.
I enjoy walking along the lakes, that many hundreds of years ago were constructed to imitate the Seine in Paris and do it very successfully.
