A walk on the topic of Art in the public space of the center of Zagreb includes permanent realizations, but also a memorial to works of art of temporary duration, as well as proposals for urban interventions. This time machine through public sculpture and contemporary art interventions in the very center of Zagreb takes us back to the formative period of contemporary art / conceptual, new artistic practices in the local context of the 1960s, 70s and eighties and outlines continuity with contemporary art practices today.
