Stockholm is often called poetically "floating city" and there is no exaggeration in that. Its oldest part is located on the small island of Gamla Stan, a tangle of picturesque narrow streets, almost unchanged since the Middle Ages. It's easy to get lost here, and that's what's most enjoyable. While visiting the capital of Sweden, I could not deny myself participation in the changing of the guard ceremony and a visit to the museum of the ship "Vasa".
