There were 153,842 Mediterranean sea arrivals to Italy in 2015: as summer began, the landings dramatically increased and Italy's neighbouring countries tightened their border controls, preventing the stream of migrants from continuing their journeys to northern Europe.
Hundreds of them, mostly from Eritrea and Sudan, found shelter inside the train station of the Italian coastal town of Ventimiglia or a few miles away, on a strip of rocks on the shore overlooking the French border.
Few of them eventually made their way to Paris and beyond taking a northerner route through the Alps; all the others were dumped by the French authorities, trapped in an endless, Escherian loop.
