Founded in 1977 to enable what was then called Mitmachkultur, cultural participation for everyone, the zakk is one of Germany's oldest and largest sociocultural centres. Since the early 1980s its regular programme has run in a converted factory hall on Fichtenstraße 40 in Flingern. Jochen Molck directed it from 2004 to 2022.

The name zakk stands for Zentrum für Aktion, Kultur und Kommunikation, and its programme is grouped under Wort und Bühne, Politik & Gesellschaft, Musik and various projects, plus discos and events on new media and the internet. In 2017 more than 150,000 visitors attended over 900 events, large and small. The house treats culture and society as inseparable, addressing social and political questions with cultural means.

The zakk occupies a converted factory hall at Fichtenstraße 40 in Flingern; the entrance is on Fichtenstraße, and the venue is served by Düsseldorf's tram and bus network. Programming runs across several rooms, so check which hall an event is in before arriving. In 2017 the house counted over 900 events and more than 150,000 visitors, so popular nights fill up.

The center integrates cultural programming closely with social initiatives and community work in the neighborhood. This blend of art and grassroots community engagement sets it apart from conventional event halls.
