Note

A first series of these maps show the presence of detention facilities for foreigners (colored dots). Only the limits of the Schengen area are plotted.  Therefore, we see how the policy of detention of foreigners, far from being concentrated in the Schengen States, spreads, beyond Community borders, to so-called third countries and to Africa and the Middle East. These maps thus reflect the externalisation of migration controls at the borders of the European Union and its restrictive aspects.

A second type of map shows the presence of border crossing points. Compare this map with the previous ones. It allows to highlight the invisibility of foreigners’ detention, since many migrants are arrested and confined in these places that are in no way intended for the reception of migrants.
