Since antiquity, philosophers and architects have imagined cities as human bodies, with arteries and veins through which pedestrians and traffic stream. Larissa Fassler on the other hand uses her own body as a measure to explore and map—or rebuild in huge models—places in cities like Berlin, London, or Paris. She did this in her work Regent Street/Regent's Park that is part of the Deutsche Bank Collection. The Canadian artist investigates how exemplary urban architectures determine our thinking, our movements, and our interactions. Lukas Freireiss followed Larissa Fassler around.
