Residents of Porte de Clignancourt and a pigeon defense association denounce the installation of a construction net under the bridge. The City of Paris installed these nets at the end of January to prevent birds from settling in and depositing their droppings on visitors to this tunnel.
Since 2006, with the SNCF, the City has been rehabilitating the Petite Ceinture - where after decades of abandonment nature had reclaimed its rights. The idea? “Protect – from droppings – walkers walking under the tunnel vaults”
