This article focuses on the local artistic networks the European artists as Gertrudis Chale, Luis Seoane or Grete Stern integrated and contributed to develop in Buenos Aires (Argentina), a main arrival city (and port) in America. In the first half of the 20th century, the city was a major urban centre where hundreds of exiled artists – mainly European – settled, as they were looking for better economic and socio-political conditions. While providing a strong focus on the crucial role and impact of local personalities and institutions, this paper has attempted to reassemble these interactions of exiled artists in modern Buenos Aires and to highlight the multiple internal dynamics of migrant networks and local networks, as well as the role of these social constructions within the mechanisms of global mobility.
