Square du Docteur-Grancher

The Square du Docteur-Grancher is defined by a steep, terraced green slope that hides a history of structural failure. Located in the twentieth arrondissement, this space sits directly above the long tunnel of the Petite Ceinture railway. The ground here was once so unstable that an entire city block, including three streets named Voulzie, Westermann, and de la Cloche, had to be demolished because the buildings were sinking.
