Having visited the exhibits at the Cité de l’architecture et du patrimoine with Alkis earlier, on Monday we took time to experience their unbelievably beautiful architecture library. Students were given time to rummage around, sketch, and actually enjoy some peace and quiet. Wednesday we were off to the Musée des égouts de Paris. Only just below the surface, the museum walked us through the history, artifacts, and complexity of the Parisian sewer system. Luckily we paid extra to be bathed in the smell.
