Marion takes us along Paris's Canal Saint Martin, which is part of a waterway network that measures one hundred thirty kilometers long. In their heyday, the Parisian canals were the main means of transportation of goods and materials, and even drinking water! Nowadays, historic buildings, restaurants, and concert halls are the main attractions along the canals.

Marion walks us through the Buttes Chaumont, a former limestone quarry transformed into a magnificent park, complete with an artificial lake, a grotto, dramatic cliffs, and even a Roman-style temple. On a more tragic note, the park is also home to a bridge that the poet Louis Aragon once called a "mecca for suicides." Luckily, the bridge is now protected by a wire fence.
