This dissertation analyzes the effects of Brasilia s construction, as a materialization of modern utopia in the southern hemisphere, more precisely, in Brazil. We investigate how modern utopia is a product not only of rationality and technical development, but also of will and faith, something that introduces it to religious nuances. In that sense, Brasilia becomes a paradigmatic case of study, because it results from a convergence between the ideals of modern architecture and a mythical genealogy that foresaw the construction of a capital in Brazil s central plateau as a means of unleashing the flourishing of a great civilization in a paradise of abundance, a paradise that later would be proved lost, unleashing melancholy and disillusionment. From this angle, we analyze unconventional readings of the event, extracted from the classics of Brazilian literature, and also mobilize the theoretical framework of allegory, derived from the work of the German philosopher Walter Benjamin, in order to construct an unconventional interpretation of Brasilia, beyond the boundaries of traditional historiography and its linear logic.
