Francesco Salvini asks what it means to translate the categories of postcolonial thought in the practices of organisation of a subaltern neighbourhood trapped in the hurricane of valorisation and abstraction of urban space. Salvini presents an analysis of what he calls an ‘audio-visual inquiry’ conducted by a collective of political activists organising in the Raval in Barcelona. The laboratory of Postcool sought to find ways to learn about the subaltern histories of the Raval that are made invisible. Salvini discusses the ways in which the collective investigated how these subaltern histories of the Raval inscribe themselves in the urban design of the city in their relevance for organising against gentrification in the context of postcolonial capitalism.
