This project aims at an understanding of Heidegger's 'topology', his thinking of spatiality and place. It focuses in particular on the 'Kehre' in Heidegger's thought in the early 30's, which will be interpreted as a turning to topology. Allthough the topological question is not absent in the philosophy of the early Heidegger, it is quite clear that the 'place of place', especially in Sein und Zeit, is highly problematic. The reason for this is not only the primacy of temporality, but also the absence of an understanding of authenticity that takes into account the importance of place. Thus, the 'topological turn' (right) after Sein und Zeit goes together with a shift in Heidegger's understanding of authenticity that implies the recognition of the importance of spatiality and place for a true 'being-there'.
