Free entry on the first Sunday of every month!

Every first Sunday of the month, the museum opens its doors to you free of charge. To guide you through the fascinating world of the sewers, our team offers free guided tours and workshops.

Bring the whole family and let yourself be amazed by our various themes, combining discovery, exploration and scientific curiosity!

No places left? Then be sure to ask at reception for our discovery guide for children or the audio guide in which you are the hero of the story.
