The Paris Sewer Museum The Paris Sewer Museum is located under the Left Bank. Visitors get a guided tour of a portion of the impressive system that outlines the history of the rat-infested place (the inspiration for Les Miserables). It's parallel to the Seine, so after you emerge from from the city's underbelly you can bask in the beauty of its famous river. Admission: about $6, with discounts for seniors, students and children. in Travelwith francemuseumparis
