This contribution explores the EU strategy of containment in Serbia trough critical mapping, analysing the construction of camp facilities after the closure of the Balkan corridor. It consists of a series of maps of camps built in Serbia in the last years, developed by the author. From 2015 to 2017, the state of Serbia has rehabilitated, refurbished, and built new camp facilities using European funds. Following a European strategy of containing and impeding migration movements from south to north, Serbia has kept thousands of people outside of the western EU territory. Whether under the label of transit, reception, or asylum centres, camps have pushed, held, and left thousands of people on the move hopeless, without clear future alternatives, living in legal and humanitarian limbos for years. These maps critically present how these infrastructures serve an EU strategy of containment and deterrence, redrawing the geography of migration in the region. Using official and available data, this work shows infrastructures, numbers of people, and funds. It focuses on a time frame beginning from the closure of the Balkan corridor to the present time. Within few years, the once open Balkan corridor across the former territory of Yugoslavia became a field to experiment the EU strategies of containment.
