This chapter explores the intersections between the notions of “urban interior design” and “public space” in West African cities. The artistic dynamics at work reshape the spaces by discussing their colonial imprint and the symbolism they have successively been charged with. As the nature of the projects is very diverse, both in terms of techniques and materials used and the objectives pursued, there is a clear desire to take greater account of the human dimension and to establish connections between local roots and the globalizing push. Through the analysis of some experiments carried out in Dakar, Cotonou, Porto-Novo, and Douala, the author identifies seven trends. The examples presented her relate to one or more of them. The projects combine the aesthetic approach with an ethical message: they translate into a citizen commitment to better, fairer, and more inclusive spaces.
