In the open air, the streets of Brussels become a true art gallery. This route explores a vibrant urban landscape where comics and street art enter into dialogue with architecture and the everyday lives of residents. From the emblematic murals of the Brussels Comic Book Route to contemporary interventions scattered throughout the city, it highlights an artistic heritage accessible to all and embedded directly in public space. Façades become surfaces for expression, walls tell stories and characters take their place in the urban landscape. Beyond aesthetics, the route also questions the role of art in the city: as a tool for storytelling, for giving value to neighbourhoods, for making claims or for creating social links. It shows how these works help redraw urban landscapes by making them lively, accessible and constantly evolving.
