The “Blueberry” is a new built multi-purpose facility in the disadvantaged inner-city area “Flughafenkiez” in Berlin’s Neukölln district, which was inaugurated in September 2024. It was initiated by the neighbourhood management and combines in an unique way youth work, community development and library work. There is a 20-year long trustful cooperation between the neighborhood management and the public Helene-Nathan-Library, which resulted in this new building to experiment with new approaches of library work and outreach programmes for communities, which normally do not visit a public library. The “Blueberry” is also a test case to change the public library work in the district of Neukölln, which is currently setting up a new strategy for its four public libraries.
