In a context of increased urban competition, art and culture are often used by cities world-wide as tools to improve their image and make urban spaces attractive. In that process, art is—as we will argue—becoming a new urban norm, which is normalizing not only urban space and experience, but also art itself. By contributing to the pacification or securization of public spaces, art could encourage some behaviors or, on the contrary, discourage others. Reversely, this normative dimension of urban art could impact art itself, especially by redefining the limit between artistic forms that are either inclusive or exclusive, dominant or subversive. Through examples found during PhD fieldwork in Montreal and Johannesburg, we will demonstrate that this normalization of the city through art and of art through the city takes place in various urban contexts, that it questions the distinction between Northern and Southern cities, and the definition of a (global) city itself.
