This paper comparatively addresses the emergence of three Latin-American Catholic sanctuaries: Virgen de Copacabana and Señor de los Milagros de Lima, both of colonial origin (Peruvian Viceroyalty), and Virgen del Rosario of San Nicolás (Argentina, since 1983). Using an anthropological perspective, through archive research with an ethnographic approach, the primary actions and motivations that helped consolidate these sanctuaries are analyzed. Who were the material and symbolic producers of these Catholic images and in which circumstances did they act? How did they become places of devotion? Which was the role of the miracles in cult consolidation? I will examine the possibility of recognizing regularities and common logics in these processes, analyzing to what extent they express either contextual factors or Catholic sanctuaries typical dynamics.
