On 26 April 2011, the Budapest city council had accepted the changes proposed by Mayor István Tarlós about the renaming of 256 squares and streets. This was the third great wave of renaming since 1989. A similar use of the public space can be observed in other former socialist capitals as well. The various changes and processes can be registered in dealing with the urban public space: There are on the one hand, new forms of urban interventions, thanks to the internet (such as flash mobs, critical mass, graffiti, etc.) which, cross-linked with civil society activities, often point to new claims of various agents on urban public space. On the other hand, the control of urban public space became centralized and often derived from former socialist „trained“ understanding of public space. In this context, the workshop discusses different questions.
