Heritage Days 2026 in Issy: this royal estate opens its doors for free
Every year, the third weekend of September marks the return of Heritage Days 2026, a cultural event that thousands of curious visitors look forward to with excitement. Private and public venues open their doors, often free of charge, to bring our shared history to life. This year, the Hauts-de-Seine department and the city of Issy-les-Moulineaux are once again fully on board.
A cultural event rooted across the entire territory
Heritage Days 2026 reach every corner of France, from Paris to the Île-de-France region. Museums, châteaux, churches, ministries and embassies all take part in this sweeping annual programme. Each edition grants access to places that are usually closed to the general public.
Unusual activities and exceptional openings make every weekend one of a kind. Visitors enjoy tours that are often free and open to all ages. It is the perfect opportunity to discover the treasures of our heritage.
These days go far beyond simple tourism. They forge a strong bond between residents and their local history. Every monument tells a chapter of our collective past.
Hauts-de-Seine, a department fully committed
The 92 department, located just west of the capital, enthusiastically joins the Heritage Days celebrations. It shines a spotlight on its historical and artistic gems, which are often unknown to the wider public. It is a rare chance to see these places from a completely different angle.
Some sites, however, remain largely out of sight for the rest of the year. Heritage Days 2026 change that for these discreet monuments. The public can visit them in a festive and welcoming atmosphere.
“Heritage Days are the perfect opportunity to make the most of great cultural experiences.”
