Windowless gable walls were graffiti painters’ early targets, particularly in urban areas under renovation, and since 2012, monumental graffiti is in full rebirth especially in Paris’ 13th arrondissement. Through a design thought as a décor, obliterating the blandness of the walls, artists skillfully revive these soulless surfaces. Out of reach, out of trends and timeless, neo-muralism benefits everyone: residents, politicians, local authorities, gallery owners and artists, and feeds another phenomenon: urban arts tourism. Authentic street-art tours attract an increasing number of visitors around this new heritage. Outside official muralism, artists working illegally are rare, in great part due to the technical constraints of the craft. Will the near future see vandalism affiliates going over monumental murals?
