This thesis deals with the treaty of Utopia and its controversial relation to the place. Research is triggered by the need to interpret the distant, non-real and impracticable, concepts that are inherent in the institution of Utopia and need investigation, in order to thoroughly understand the term. The place where the ideal treaty will be settled is an enigmatic element of its existence; for this particular reason, two possible places for housing the utopian desire, that of the island and that of the city, are examined.
The research consists of three fundamental themes. In the first section, the concept of utopia is approached, both etymologically and historically, as an integral part of philosophy. The factors for the utopian thought are presented, mainly by the defining one of the subject, who is self-defined by his personal desire and the anxiety of fulfilling all his needs. In addition, the specific vocabulary of utopian conception, as well as the major definitions necessary for the understanding of the term, are analyzed. In the second section, the question of the place of Utopia is considered, taking into account the utopian literary texts and drawings of the last centuries. Most utopian writers have decided to house the ideal social structures they describe on distant islands, impossible to approach and map. That is the reason why they were called utopian. Interestingly, the organization of the utopian society, which, without any exception, was organized, served the institutions of the urban treaty in all its manifestations. Then there are comparative readings concerning the city and the island respectively, resulting in common places within the existence of both, intersections in their lives, which will be considered necessary for the spatial fulfillment of the utopian desire. Finally, comparative reading of the utopian texts leads to the production of quality diagrams/symbols, capable of describing schematically each utopia, but without aspiring to create its place of habitation. In the last section, the Archipelago Treaty is extensively analyzed, as a place of aggregation of elements with common features, which are an integral part of it and constitute an indivisible whole, despite the fact that can be taken as autonomous beings. The new utopian symbols are collected and set up an archipelago of utopia, a new imaginary place of cognate points, originating from the common matrix of the individual desire for impracticality and encounter with the unfamiliar, creating a continuously developing fantasy map, a new place for utopia.
