From 2015–2020 Schlosspost has become a dynamic transdisciplinary online platform for artistic research. It addressed current issues in art, culture, society, and the digital world, and provided insights into the practices of international artists and scientists. It allowed visibility to Solitude’s network of alumni, friends, and experts in more than 120 countries, promoting new political voices and collective discourses in an open and sustainable space. By exploring new forms of art publishing and writing, Schlosspost combined critical and serious – but also playful – attitudes and ways of thinking. Schlosspost remains an open archive to a multidimensional world, as well as transversal forms of knowledge and alternative futures. We would like to take this opportunity and thank everyone involved in this project.
