In Vénissieux, near Lyon, a social landlord decided to install metal barriers around a group of old buildings in the city center. To pass through the secure gates, you must now have a badge.

A decision by the social landlord, Sacoviv, which was a necessity in the face of drug trafficking, explains its director, Roxane Michel. “The objective is for our tenants to feel safe and peaceful without having drug dealers intrude into their living space, as could have been the case before," she says.
