The Modern Movement in Architecture gained ground in the first decades of the 20th Century as a proposal of radical rupture with the past, willing to establish a new aesthetic in tune with the spirit of the industrial era. Not wanting to disregard the deep changes which the new language produced in architecture, this dissertation aims to investigate the possible dialogues between modern works and classical tradition, having in mind buildings of Brazilian architects. The discussion is inserted in the recent debate of Brazilian historiography, which intends to approach the modern architecture taking into account its multiple aspects, highlighting ambivalent qualities which make the works more complex and interesting, as the international critic has been showing for some time, especially with the interpretation that points to the relations between Le Corbusier and the classical tradition. Among the works distinguished in this analysis are the headquarters building of Ministério da Educação e Saúde do Rio de Janeiro (Education and Health Department of Rio de Janeiro, 1936), by Lucio Costa and his team, with consultancy of Le Corbusier; the palaces of Brasília by Oscar Niemeyer (Alvorada, Planalto and Supreme Federal Court, 1957-58) 1957-58) Court and the building of the FAU/USP (College of Architecture and Urbanism of São (College of Architecture and Urbanism of São Paulo University, 1962- 69), by Vilanova Artigas. The choice of representative and, at the same time, varied examples of the Brazilian production allows us to understand the different forms with which the Modern Architecture has established relations with the classical tradition, especially when it aimed to embody in the buildings the emblematic ideals of its historical time.
