I find myself in Copenhagen on business. I can now confirm via personal experience that Christiania is indeed an interesting place. Very few of my friends in the US had heard of this place, and indeed I hadn't either until a work acquaintance recently hipped me to the existence of this self-proclaimed autonomous state in the middle of the city. Does the existence of a second "free zone" (outside, of course, of Amsterdam and, indeed, the rest of the Netherlands) register in people's consciousness in the UK? How about in the Netherlands? And when I say "people", you know who you are.
