Christiania, also known as Freetown Christiania (Danish: Fristaden Christiania or Staden), is a self-proclaimed autonomous neighborhood of about 850 residents, covering 34 hectares (84 acres) in the borough of Christianshavn in the Danish capital Copenhagen. It was temporarily closed by residents in April 2011 while discussions continued with the Danish government about its future, but then re-opened to the public.

Christiania has been a source of controversy since its creation in a squatted military area in 1971. Its cannabis trade was tolerated by authorities until 2004. In the years following 2004, measures for normalizing the legal status of the community led to conflicts, police raids and negotiations. (Wikipedia)
