Modernity is related to the evolution and consolidation of the city, which would become the topos of its thought. Paris, Madrid and Barcelona were at once art’s centres of production and its stages, and at the dawn of the twentieth century cities’ growth and modernisation via urbanism and architecture brought about major social and cultural change. Thus, the newest art left behind official spaces to search for different forms of dissemination and communication in galleries, small exhibitions, publications and magazines, the new spheres of encounter and discussion that shaped modernity. In the 1930s, owing to the social and political events that took place across the decade, many artists took a public stance and turned not just art but also its locations into places of transformation. More than ever, the city would be recast into a framework for art to be presented.
