The Alpine territory, became, after the so-called "long summer of migration" (2015), a real obstacle for certain groups of people, the "indésirables" (Agier, 2008). Refuge seekers willing to reach the countries of central and northern Europe, encounter almost insurmountable barriers at the South-Alpine borders, that become, as at the beginning of the 20th Century, a line of friction and tensions. Thus, the southern border of the Alps, after having become invisible with the introduction of the Schengen Area in 1995, re-materializes. Thus, the political response to the arrival of refuge seekers transformed the Italian Northern borders to a sort of new external border of Europe. I will therefore discuss this process, described by Heller and Pezzani (2016) as an "internal externalization" of borders.
