Overview

• The City of Paris has announced the opening of three supervised public swimming sites in the Seine on July 5, 2025.
• These sites, located near the Eiffel Tower, Notre-Dame Cathedral, and the National Library, will include amenities such as changing rooms and sunbathing areas.
• Daily water quality testing will be conducted, with swimming suspended during heavy rainfall or strong currents to ensure safety.
• Over €1.4 billion was invested in cleaning the Seine, including connecting 2,000 households to sewers and building a 50,000 m³ stormwater overflow basin near Gare d’Austerlitz.
• The initiative is framed as both a legacy of the 2024 Olympics and a strategy to enhance urban livability during increasingly hot summers.
