ABSTRACT
A gradual increase in the number of initiatives aimed at collecting, storing, and managing personal data about citizens can be observed in various countries, regardless of their political regime. Privacy concerns are often undermined in face of the feeling of insecurity in public spaces. The securitization of urban spaces, as well as the use of technologies and strategies for monitoring activities, individuals, and groups, is part of a package of changes imposed by the organizers of mega-events that have been called 'legacy'. Mega-events helped to boost surveillance schemes and justify the huge investments made to build and operate them. This chapter focuses on a dimension of the spatial network formed by video surveillance that is overlooked in urban studies about securitization: the work of the watchers. On some occasions, specific prominent buildings are the focus of monitoring. The chapter explains the territories, the control of spatialities, and the challenging of boundaries as a core sociotechnical arrangement of cities.
