An essential component of the sustainability of cities is “public space” for numerous political, social and economic reasons (see only Thompson, 2002; Tonnelat, 2010). However, the main trend for at least the last half century was to shrink rather than to expand public spaces (Kohn, 2004; Castells, 2008; Low and Smith, 2006). This enclosure of the urban sphere took place for several reasons. Indicative are the suburbanization; the technologies of surveillance, like cameras, which arise ethical issues for citizens’ privacy; the gated communities containing strictly-controlled entrances for pedestrians, bicycles, and automobiles; and condominiums (see only Tonnelant, 2010; Low and Smith, 2006). More importantly, the diverse processes of public space privatization, which took place in many cities worldwide through the wave of emergent local and national politics, have led to this phenomenon (Harvey, 2006; Gehl, 2003; Castells, 2008). In addition, this privatization could be seen as a manifestation of New Public Management practices (see only Drechsler, 2005) which arguably has an impact even on urbanism.
