There is an unfair gap in the urban history of Brasilia, where it is found many researches about the Plano Piloto of Lucio Costa (Pilot Plan of Lucio Costa) and few investigations on urbanistic plans of the Satellite towns such as Ceilândia, that gives material to understand better the history of the metropolis of Brasilia. Facing this acknowledgement, this dissertation proposes to analyse the urbanism of Plano Piloto of Ceilândia (Master Plan of Ceilândia), designed by the architect Ney Gabriel de Souza, together with reflections on socio-spatial notions for a better understanding of the right to the city. Such interweaving has strict link with the history of Ceilândia. It was built between 1969 and 1971, and through the Campaign to Eradicate Invasions (CEI) and its anacronym is the base for the full name of the city. The city at the beginning was the result of an emblematic moment of urban-spatial segregation of intra-urban history of Brasilia. In this proc-ess, about 83 thousand people were removed to over 30 km far from Brasilia, the Plano Piloto of Lucio Costa, out of very detailed policy of deterritorialisation of the unwanted slums. There was even the intriguing justification that this invasions and slums were locate within the sanitary protection ring of Brasilia. Thus, the undertaken analyses are based on an approach rooted in the urbanistic practice, with subjacent reflections around the multiple concepts used in the socio-spatial studies. In this sense, I search to approach the urban aspect of Ceilândia by tackling the issue from inside to outside, and exploring the conceptual tensions of hegemonic discourses. Above all, the discourse of the limiting dichotomy downtown-periphery - even facing the reality of over 400 thousand current in-habitants - Ceilândia tends to be placed out of the centre of the question. Regard-ing the city s design the analyses of the project planning practices in the conformation of the spaces, elaborated in deep detail, will allow to clarify the intention of the Master/Pilot of Ney Gabriel, trying when possible to express the self-representation of Ceilândia in the process of appropriation of urbanistic plan. From bibliographical reviews, iconographical and journalistic materials, the analysis has as its focus the guidelines of the original project done in the 70s.
