Christiania, also known as Freetown Christiania (Danish: Fristaden Christiania) is a self-proclaimed autonomous neighbourhood of about 850 residents, covering 34 hectares (85 acres) in the borough of Christianshavn in the Danish capital Copenhagen. Civic authorities in Copenhagen regard Christiania as a large commune, but the area has a unique status in that it is regulated by a special law, the Christiania Law of 1989 which transfers parts of the supervision of the area from the municipality of Copenhagen to the state.
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. Since then, measures for normalising the legal status of the community have led to conflicts, and negotiations are ongoing.
Among many Christiania residents, the community is known as staden ('the town'), short for fristaden ('the freetown').
