The sprawling public park challenges traditional ideas of sculpture by specializing in works that often require participation rather than spectatorship. The public art is that of relational and social sculpture in collaboration with local communities whose aim is to present world-class artistic production in a non-institutional, democratic context. Not all artworks are permanent and material, some are based on interaction with the audience during concerts, workshops or even processions, and gondola rides. Participating artists have included Paweł Althamer, Olafur Eliasson, Jens Haaning, Susan Philipsz, Katarzyna Przezwańska, Monika Sosnowska, the group Nowolipie, Youssouf Dara, and Rirkrit Tiravanija.
