At Slagen, Hudøy and several other places, Oslo Municipality drove holiday colonies where children from the city could vacation in the summer. At Dal there was a separate holiday colony for tuberculosis-infested children. Some children were also sent for holiday stays on farms. More than 5,000 children received a stay at municipal or private holiday colonies every summer. ***** Oslofilm was a series of public information films about life in and around Oslo, produced between 1940 and 1980. Funded by the state, the films offer valuable insight into postwar Norwegian society.
