Even though the summit on global warming held here in December last year was considered by many a failure, the Danish capital was confirmed as one of the most “green” cities in Europe. True protagonists of the “green revolution” are the long bicycle trail that traverses each city thoroughfare. Here bicycles can be rented for free. And because Copenhagen got through the so-called “re-qualification of urban areas”, Nørrebro, once an ill-famed neighborhood, now has turned into one of the preferred areas of students and intellectuals who meet in the Sankt Hans Torv Piaza. Fun is guaranteed, and the premises are open till morning.
