This lecture explored how memory functions in the social sphere and how it is reflected symbolically in the space of the city. Conceptual artists Stih and Schnock discussed how the intrusion of art in public space affects everyday life in memorial projects, including “Places of Remembrance,” “BUS STOP,” and interventions like “Invitation” at Berlin-Alexanderplatz. Collections as containers of memory will be explored, including “Who Needs Art, We Need Potatoes,” “The Art of Collecting - Flick in Berlin,” and, most recently, “The City as Text” and “Show Your Collection.”
