Refugee camps have been multiplying at the gates of the European Union since the escalation of the Libyan and Syrian conflicts in 2016, particularly in Greece and Italy. These countries, which act as the main gateways, are implementing a "hotspots" approach included in the European agenda on migration established for the period 2015-2020. At the same time, restrictive migration policies combined with structural difficulties within the formal education system are encouraging the emergence of educational complexes directly within the camps. The objective of this article, which focuses on the situation in Greece, is to demonstrate to what extent the development of these complexes is modifying the environment of the camps to the point of changing the very essence of their definition.
