Christiania is a freetown area that began back in 1971. At that time the area was an abandoned military base and squatters moved in. Since then the area has gained some recognition by authorities with a law that enables the area to enjoy some level of self governance. For instance, the area has open cannabis trade in the center market place and many of the buildings you can see are very creative and don’t exactly follow regular building codes. It is one of Copenhagens most visited tourist attractions.
