Get out your diaries, the great cultural festival of the autumn is back: on September 20 and 21, 2025, the Journées du Patrimoine celebrate their 42nd edition in Paris and the Île-de-France region. As every year, this event gives the public the chance to visit thousands of famous and little-known sites in cities across the country.
Museums and castles, factories, backstage department stores, prestigious schools, theaters and gardens, as well as train station technical centers, historic monuments and hidden townhouses: French history and heritage come to life in these exceptional places, which open their doors to all visitors.
In Paris, the Heritage Days are an opportunity to discover some amazing sites, including a historic monument built by Gustave Eiffel himself... No, it's not the famous Tower! But an industrial laboratory designed to test the aerodynamic properties of aircraft and cars. This Eiffel wind tunnel, inaugurated in 1912, is still in operation today. The site rarely opens its doors to the public, so don't miss this opportunity to visit!
Aucun événement annoncé à ce jour, le programme est mis à jour en fonction des annonces officielles.
And, of course, don't miss the special tours of the Eiffel Tower during these Paris Heritage Days.
