THE CONTRIBUTION OF FENCES AROUND URBAN PARKS - REFLECTIONS ON THE PUBLIC SPACE AS A COMMON GOOD.

This thesis addresses the issue of urban parks and public gardens as a commons in order to understand the contribution of their fences to public space.Urban parks are part of the public space. But what is public space today? There are two dimensions that form it: spatiality/physics and society/politics. Public space is also a commons - a commons in both senses of the Common Good and the Commons. The concept of landscape is omnipresent. These recurrent polysemies of key notions will be discussed in the dissertation, on the one hand by drawing on theoretical research and on the other hand by making sensitive analyses, in urban parks in Paris, witnessing different times and issues. Links and barriers between these and their surroundings are studied.
