Christiania in Copenhagen, Denmark is an independent community of almost 900 people founded in 1971 on the site of an abandoned military zone. In Copenhagen, as in other European cities such as Berlin and Amsterdam, the squatter movement was large in the 1980s. It was a social movement, providing housing and alternative culture. A flashpoint came in 1986 with the Battle of Ryesgade. Another flashpoint came in 2007 when Ungdomshuset was evicted. While not technically a squat until 14 December 2006, it was a social centre used by squatters and people involved in alternative culture more generally. After a year of protests, the city council donated a new building.
