Lionel is still in Liverdun, a small village in the Lorraine, to find out some more about the madeleine. It's a specialty of the region that comes in various delicious flavors, such as mirabelle plum and bergamot orange.

Lea shows us one of the largest film libraries in the world, the Cinémathèque Française, which contains over forty thousand films. After the Cinémathèque's original home in the Palais de Chaillot burned down, it relocated to a brand-new facility in Paris's twelfth arrondissement.

Meet Jean-Claude and Rachelle, who own a specialty store full of delicious goodies. They talk to Lionel about the madeleine, a specialty of the Lorraine region that was supposedly invented by a cook named (you guessed it!) Madeleine.

Aldo takes us to a very special house on 23 Rue Beauregard in Paris. In that house lived a shady character, Catherine Deshayes, who was responsible for the murder of thousands of infants. She and 36 others were burned at the stake by Louis XIV.

Lionel takes us to the friendly Butte aux Cailles neighborhood in Paris. Its village-like atmosphere is a welcome respite from the hustle and bustle of the capital. The Butte aux Cailles was formerly part of the small town of Gentilly before being attached to the city of Paris.

Lionel and Jean-Pierre conclude the Lindre-Basse series from the top of a wildlife observatory overlooking the Lindre pond. It's a very fragile area filled with bird life that deserves protection.

The quaint little town of Montmorency holds a few peculiar surprises, such as a gas station sign with an outdated phone number and a statue of Jean-Jacques Rousseau that's been knocked over multiple times.

Jean-Pierre teaches Lionel some more interesting facts about the birds of the Saulnes region. For example, did you know that a swan can eat up to three kilos of grass per day? How's that for a vegetarian diet!

Daniel Benchimol shows us around Montmorency, a town famous for being the residence of the Enlightenment philosopher Jean-Jacques Rousseau, who lived in the "House of Gossips." Montmorency also boasts a medieval communal oven and is near a sulfurous spring that is open to the public!

Jean-Pierre gives Lionel some more information about the habits of storks. These migratory birds can be trained to be sedentary so visitors have a chance to see them year-round.

Daniel takes us north of Paris to Montmorency, a charming little town with a collegiate church called the Collégial Saint Martin. This historic town is only a stone's throw away from the ultramodern business district of La Défense.

Still in the Lindre-Basse region, Jean-Pierre explains the fish breeding process to Lionel. They also enjoy the beautiful sight of storks building their nests during mating season.

Lionel and his cousin Jean-Pierre continue their visit to the Lindre-Basse area with its amazing natural surroundings. The ponds teem with fish and birds for a while before being drained and then used for cultivation, which in turn will enrich the soil after they're refilled.

Lionel is in Toul, twenty-seven kilometers from Nancy in the northeast of France. This small medieval town has a pretty riverside port and a magnificent Gothic cathedral called Cathédrale Saint-Étienne. Don't miss Lionel's signature pun at the end of this video!

Lionel and Jean-Pierre talk about fish farming in the pond of Lindre-Basse. This practice dates back to the Middle Ages with an order of soldier-monks called the Knights Templar.
