The Journées du Patrimoine are back in Paris! Saturday 20 and Sunday 21 2025 are an opportunity to discover cultural sites often closed to the public, such as the Hôtel de l'Industrie.

This year, the Journées du Patrimoine 2025 will take place on Saturday September 20 and Sunday September 21. Initiated in France in 1984, the aim of these days is to promote cultural and architectural heritage by enabling visitors to discover places that are usually closed or not easily accessible, such as theHôtel de l'Industrie, which is scheduled for a guided tour on Sunday September 21.

The Hôtel de l'Industrie, located in the heart of Paris's Saint-Germain-des-Prés district, is a prestigious historic building constructed in 1823. Originally designed to house exhibitions and meetings linked to the industrial and scientific advances of the time, the Hôtel rapidly gained in importance, becoming a meeting place for engineers, inventors and entrepreneurs, playing a crucial role in the spread of industrial innovation in France. The site is opening its doors for the Journées du Patrimoine 2025 with a guided tour.
