In 2021, Gothenburg celebrates its 400-years anniversary. In order to optimize the humanistic collaboration project "Gothenburg Cultures on the Town 1621-2021 (GPS 400", which is performed 2019-2023, the applied communication project undertakes meetings, seminars, workshops, conferences, inventories, exhibition planning, applications, and also creates basic structures for a digital project platform as well as for advisory boards, expert groups, and commissioned courses. The aim is that these activities result in a mutually rewarding and fully functioning project structure, in reliable channels of dissemination such as a freely accessible project platform, in innovative collaborative activities where digital techniques meet "humanities on the town", and in co-creative research, education, and collaboration together with local participants both during and after the project period. By regarding, understanding, and using the cultural history and future of Gothenburg together with colleagues, students, authorities, cultural institutions, businesses, citizens, newly arrivals, and visitors in explicitly collaborative ways, the applied communication project establishes the base for a complete academic context, within which research, education, and collaboration interact effectively and sustainably with society at large.
