Freetown Christiania, also known as Christiania, is an intentional community and commune of about 850 to 1,000 residents, covering 7.7 hectares (19 acres) in the borough of Christianshavn in the Danish capital city of Copenhagen. 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, relations between Christiania and Danish authorities have been strained.
