About this event
For one day the sewer museum under the Quai d'Orsay drops its admission charge and programmes the Fête de la science inside its tunnels: how Paris moves its water, who maintains the network, and what actually happens beneath the pavement. Properly odd, properly educational, and genuinely underground.
Why we picked it
The Paris sewers for nothing, for one day only, with science programming laid on.
