Seeking thus to contribute to the analysis of contemporary challenges of planning built heritage conservation in Brazil, by recognizing the dichotomy between orthodox and heterodox theories of conservation (meaning of Lixinsky and taken over by Wells, 2015). In the heritage conservation management field as well as in the academic field of research on heritage preservation in Brazil, difficulties in the application of the principles and assumptions of the property cards and other official documents of which Brazil is a signatory, as UNESCO's Conventions, for example, are often criticized. The basic law of preservation of the Brazilian national heritage (Decree-Law No 25/1937) and conservation practices are based on a theoretical framework of European origin, whose same premises date back to the pioneering efforts of heritage conservation of the Renaissance in Italian Quattrocento (Choay, 2001). Far from denying the importance of the trajectory of heritage preservation in Brazil, which saved numerous monuments of destruction in its heroic phase (Fonseca, 2005), it must be recognized that today, in the face of intense social and urban changes in globalized cities, we face with huge technical, social, cultural, political and economic challenges in the field of heritage conservation.EnglishopenAccessconferenceObject837-841
