The Gare de la Chapelle lies on the North-South link between Bruxelles-Midi and Bruxelles-Nord railway stations and has apparently been surrendered entirely to graffiti artists, whose work has then been further “decorated” by other graffiti. These photographs were taken beneath the bridge linking the Rue Roger van de Weyden with the Rue Miroir and the Marolles quartier. The road is lined with parked vans (belonging, I think, to market stallholders) which are also covered in graffiti and murals.

yes, walking through that underpass and gaping at the graffiti is always a treat when i visit Brussels!
It's like a magic bridge!
