KUNSTZELLE, a former telephone booth in the courtyard of WUK, is its smallest exhibition space. For more than 15 years it has been a place for artistic installation and intervention. Around 80 artists have taken the minimal structure as a playing ground to realize various projects. In this process the site has been continually revalued. The project is curated by Christine Baumann, who initiated the project, and in 2022 Pablo Chiereghin also joined the curatorship.
