Galeria Miejska Arsenał holds exhibitions, organises educational activities, and issues a range of publications, including the online art magazine Punkt. It also makes itself available for interdisciplinary activities, opening the gallery to areas of culture outside the world of contemporary art. Arsenał also collaborates with local academic institutions and other cultural institutions in Poznań. The gallery is involved in building a collection of artwork (as part of the Wielkopolska Society for the Encouragement of the Fine Arts) and is building its own collection of artwork by artists who exhibit at Arsenał).
