This work explores the ways that brought the development of Latin American architecture to the highest extent of morphologic complexity. Understanding the evolution of forms and fusion of different traditions we can research the possibility of the progress of classical forms and ways of further possible development of the architecture and culture overall. An objective of this work is to prove that the formation of the Latin American Baroque was not an accidental combination of influences but a conscious elaboration of a universal architectural concept enabling convergence of East and West and confluence of the most various cultures in one unity. The main emphasis is put on the correspondence between the processes happening in Latin American and in Russia featuring the Eurasianist principles of cultural formation in both cases. The similar circumstances that induced the generation of progressive architecture are investigated in order to figure out the universal formation principles applicable to any kind of architectural innovation.
