Shortly after the end of the war, an innovative urban development project known as the Finger Plan was introduced in 1947, encouraging the creation of new housing and businesses interspersed with large green areas along five "fingers" stretching out from the city centre along the S-train routes. With the expansion of the welfare state and women entering the work force, schools, nurseries, sports facilities and hospitals were established across the city. As a result of student unrest in the late 1960s, the former Bådsmandsstræde Barracks in Christianshavn was occupied, leading to the establishment of Freetown Christiania in September 1971.
