Every year, Heritage Days offer the perfect chance to uncover the hidden treasures of our towns and regions. In 2026, the Hauts-de-Seine department presents an impressive program, spotlighting venues that are often closed to the public. With the themes of endangered heritage and the heritage of photography, these two discovery days help deepen our understanding of the history of this dynamic region while tracing the invisible threads that connect it to its past.
In the Hauts-de-Seine region, every place tells a story of this rich history. From the Château de Malmaison to the secret gardens of Sceaux, it's a real plunge into the past that awaits us. Strolling the streets of the département, you can feast your eyes on the fascinating monuments that bear witness to centuries of history and architectural creativity. From historic mansions and remarkable parks to museums with rare collections, each site reveals a piece of France's heritage, just minutes from Paris.
By the way, have you heard of the Journées du Patrimoine? A quick recap for newcomers: these exceptional days take place once a year, on the third weekend in September. On this occasion, Europe's cultural sites, heritage sites and institutions open their doors to the public free of charge, so that we can discover their history, their mission and their special features. You'll be able to enjoy a stroll around some of the most beautiful sites in France and Europe, and take part in the many events organized especially for the weekend.
