Rise of the zombie river
Once across the street, turn left to face curvy rue Brillat-Savarin and stop there.
It has now been about a century since the Bièvre was fully covered, and the water is apparently clean again. So the local Green Party has proposed digging it back up and turning the street itself into the river again, and the pavement you’re standing on into river banks.
Let’s see if this goes through.
In the meantime, let's get closer to your final secret village. Cross rue Brillat-Savarin using the pedestrian crossing in front of you, and keep going straight down the right hand side pavement of rue Auguste Lançon.
