Musée des Égouts de Paris

Musée des Égouts de Paris
Musée des Égouts de Paris (Pont de l’Alma, at 93 quai d’Orsay, Paris) (Metro Alma-Marceau, RER Pont de l’Alma) — this museum is dedicated to Paris’ evolving sewage system (which got its start in the 14th century, and gradually developed ever since, including Napoleon’s orders to have the city’s sewers covered).. This is a “must see” destination for any visitor who’s interested in engineering, public works, or unusual tourist attractions–and for fans of Victor Hugo’s novel, Les Misérables, and the musical that it inspired.
Admission: €4.30 (regular), €3.50 (reduced). Open Saturday to Wednesday from 11:00 am to 4:00 pm (October 1st to April 30th), and from 11:00 am to 5:00 pm (May 1st to September 30th). Closed on Thursdays & Fridays.
