This paper highlights artists’ role in creating a just city. Drawing on Jane Jacobs’ insights on the importance of design for a diverse city and her analysis of the visual order of cities, I argue that artistic interventions are prime examples of the constant negotiation processes that take place in cities. These negotiation processes affect the power relations of the urban society and contribute to constituting urban public spheres. In addition, by shedding light on the processes of producing urban public spaces at locations, for example through artistic interventions, the article emphasises the non-fixity of the city as socio-material entity. The article proposes to understand these negotiation processes and the city’s dynamic nature as central to ‘making the just city’ and to allow for equity, democracy and diversity, the key elements of a just city.
