Although some may argue that the Anarchist community of Christiania has no place in Fine Traveling, the idea is to go in, walk through the gated premises to get the feeling of a freetown, don't take pictures, don't piss off anyone and you will be fine. Oh, and don't go alone if you are a lady, especially at night.
The self-proclaimed autonomous neighborhood of about 850 residents, covering 34 hectares, has its own rules and its own authorities. And they don't arrest those using drugs. But... what happens in the controversial Christiania stays in Christiania. A foot off those gates and it's back to Copenhagen law.
