Paris 2024 Olympic Games: Anne Hidalgo invites Emmanuel Macron to dive into the Seine with her in front of the Town Hall. “If he (Emmanuel Macron) wants to come, he will obviously be welcome,” she said.

Since 2016, the State and local authorities in Ile-de-France have invested around 1.4 billion euros to make Seine and the Marne, its main tributary, swimmable. Swimming in Seine was banned in Paris a century ago (1923) by a prefectural decree.
