Musee des Egouts de Paris: France

Le Musee des Egouts de Paris, or the Paris Sewer Museum, is dedicated to the famous sewer system of Paris.

The sewer system is quoted in Les Miserables (Jean Valjean; Book II, ch.1): “…Paris has another Paris under herself; a Paris of sewers; which has its streets, its crossings, its squares, its blind alleys, its arteries, and its circulation, which is slime, minus the human form.” Tours of the sewage system are have been popular since the 1800s.
