This former mill now serves as a restaurant. You'll find an apartment hotel just across the street. It's a peaceful and pleasant setting!

Iron pedestrian footbridge built in 1893-1894 to facilitate traffic between Le Perreux and Bry-sur-Marne. The construction of the Bry Footbridge by the Société de construction de Levallois-Perret, a former company of Gustave Eiffel, aimed to replace a missing ferry and to allow Bry residents access to the Nogent tramway. It required the installation of 42 piles driven to a depth of 10 m.
