This research studies three federal programs for preservation of cultural heritage: the Integrated Program for Reconstruction of Historic Cities (PCH), officialized in 1973(PCH), officialized in , during the civil-military dictatorship (1964(PCH), officialized in -1985 and remained until 1983; the Monumenta Program, which was officialized in 1999 and lasted for around 10 years; and the Growth Acceleration Program of Historic Cities (PAC-CH), that was officially launched in 2013 and continues to these days. Despite temporal discontinuities and the different political contexts in which the public actors implemented the three programs, the conceptions of these three programs remain within the dialogue between the different government instances, having IPHAN as the structuring axis and the scope to the national territory. Besides this, the understanding of the intervention objects beyond the monument itself or the city itself as an object of intervention is a constant. This research aims to study the continuities and ruptures in the conceptions and practices related to cultural heritage in the programs, the leading national and international recommendations and the theoretical positions of the preservation trajectory that informed them. Beyond these aspects, this research investigates the repercussions of the programs on the state and municipal spheres. In this sense, understanding that the municipal sphere emerges as a crucial point for the viability of actions and the establishment of mechanisms for defining practical action, we promoted a dialogue with the preservation trajectory of the city of Ouro Preto-MG. This city can be understood as representative because it has been an object of all federal programs above mentioned/being considered in this this study , and, especially concerning the integrated vision of heritage and urban planning. The focus is the unfolding of preservation and planning strategies based on the guidelines established by the preservational federal programs.
