We live in an urban century, in which more and more people worldwide are attracted to cities. Ecological and socio-economic effects of this development are moving clearly into the focus of various disciplines. However, even our everyday life and thereby our urban living space are noticeably more closely linked with the future of the city. How to deal with public urban spaces and role citizens play in shaping these spaces, is the research interest of this thesis. Henri Lefebvres work regarding the production of space and in particular his call for a “Right to the City” provides the theoretical foundation. An example analysis is provided by a socio-cultural neighborhood festival, the Lendwirbel located in the district Lend in the city of Graz. Based on the theoretical workup and the empirical results a number of issues are presented. Significantly, worldwide trends toward greater regulation of public spaces emerge thereby. We are in the midst of a paradigm shift in terms of dealing with the strange and the different in public space. Formerly, European cities provided an ideal breeding ground for the development of democracy and tolerance. Nowadays these are threatened by cleanliness, regularity and security policies. The increase in space regulations and the capitalistic orientation of many cities, however, are being confronted by the rebellion of its citizens. Citizens are reclaiming public space in a self-reliant and subversive way. The process of appropriation, use and perception of space is therefore also the focus of this thesis.
