The main aim of the thesis is the study of the urban network of the prehistoric town of Akrotiri, Thera. The social and the political space of the town are being explored in to be educed sociological, political and anthropological connotations. The urban space of Akrotiri is being approached by three theoretical and methodological tools: Systemic Functional Theory, Space Syntax and Heterotopias as being developed by Foucault. The research concluded that Akrotiri was characterized by strong spatial fluctuations of the empty public spaces mainly due to the ondulation of the buildings. Also, the urban network can be characterized as a sensually stimulated environment where the richness of the colors and the differences of the light and dark areas were the daily experience of the town citizens. Additional, Akrotiri impresses the visitor by the great number of squares and crossroads. These would offer a plethora of choices and the sense of freedom of movement into the urban fabric of the town. The cohesion, the unity and the homogeneity of the society seems to be succeeded through the spatial pluralism and the differentiation of urban forms.
