To promote academic and research exchange among institutions, researchers, and students, the South-Eastern Europe: Four Cities (SEE:4C) initiative has fostered collaboration through a range of activities and events, both virtual and in presence. These include public seminars and lectures, joint studios, courses, and workshops, as well as exhibitions, site visits, and networking mixers aiming at fortifying connections. All the above have provided significant opportunities for knowledge sharing, innovation, and lasting international partnerships.
