Adrien talks to us about Paris's Rue des Martyrs [Martyrs Street]. There, a hapless bishop, Saint Denis, was decapitated. He supposedly carried his severed head in his hand all the way up the street. But rest assured, the street has none of this gruesome past. It's filled with restaurants, bars, cafes, and cabarets to keep you entertained and happy.

Discover the beautiful Parc des Buttes Chaumont in Paris with Adrien. This peaceful park used to be an execution site in the thirteenth century. Its gruesome past long forgotten, it is now a peaceful place where Parisians can get away from the city.

Adrien explores the Quai de la Seine and the Bassin de la Villette in Paris. This basin is the largest artificial body of water in the city of Paris. It once served as a source of drinking water, which, incidentally, was much cleaner than the water from the Seine.

Adrien will tell you everything about the Paris metro, which opened its doors in nineteen hundred for the World's Fair. It carries an impressive five million passengers per day and is one of the busiest underground systems in the world.
