Heritage Days 2025 at Château de Plaisir in Yvelines (78)

When it's time for the Journées du Patrimoine (Heritage Days), enthusiasts and the curious alike take the opportunity to discover the treasures of Paris and the Île-de-France region. Every year in September, numerous free visits, events and exceptional openings await us at a wide variety of sites, allowing us to discover their respective backstages, secrets and stories over the course of a weekend. All in all, it's a not-to-be-missed highlight in the Parisian calendar! The next event is scheduled for September 20-21, 2025, for a fascinating 42nd edition.

The castles of the Île-de-France region are of course part of this year's Heritage Days, so we're taking the opportunity to explore these impressive residences, which are also to be found in the Paris region. The département of Yvelines has no shortage of beautiful estates to discover, the best known of which is the Château de Versailles. The town of Plaisir also boasts a charming estate. The Château de Plaisir and its park are among the heritage treasures well worth a visit. Built in the 17th century, it is now a cultural hub, housing the media library, the conservatory and the Théâtre Robert Manuel, as well as exhibition and reception halls.
