The Guardian view on reclaiming the Seine: hope for 21st century rivers | Editorial

Paris 2024 has pointed the way towards a brighter future for urban waterways in post-industrial cities

It was an American modernist poet who captured best the ancient, elemental status of rivers. In one of his best-loved poems, Wallace Stevens celebrated their third commonness with light and air / A curriculum, a vigor, a local abstraction". Life-supporting and place-defining, the great rivers of the world have nurtured and sustained our cities, but more latterly been blighted by the toxic legacy of industrialisation.

The successful staging of Olympic events in a cleaned-up River Seine therefore deserves to be seen as a social and environmental milestone, as well as a sporting one. The remarkable spectacle of triathlon competitors diving from the Pont Alexandre III, as the Eiffel Tower loomed large on a blue-skied summer morning, will take some beating as a signature image of Paris 2024.
