The “Lebendige Stadt” (lively city) project’s main aim was to increase the inhabitants' feeling of security when using these underpasses. It makes these areas more livable while at the same time saving energy and cost.
Dark railway underpasses are barren places, sometimes located in deprived areas. The “Lebendige Stadt” Foundation has initiated an illumination program to revitalize these public places. So far, 31 railway underpasses in 24 German cities were permanently and artistically illuminated.
