‘Chaos at the gates of Paris’: Inside the sprawling migrant camps nobody talks about

About a hundred metres from “Crack Hill,” a patch of wasteland where dishevelled drug-addicts congregate to buy a fix and where many live rough, a sea of tents stretches out underneath a motorway flyover.

There a few hundred migrants from war-torn or impoverished countries live in appalling conditions, waiting for their next appointment with the migration authorities, who after an initial meeting send them away to fend for themselves for months on end.

There is no hard evidence that authorities tolerate this camp near Porte de la Chapelle metro station in the 18th arrondissement because it is largely out of sight, but if officials wanted to hide a settlement like this then there could hardly be a better place.
