Heritage Days 2026: an exceptional weekend in the Île-de-France region
The European Heritage Days are making their grand return to France on September 19 and 20, 2026. This unmissable cultural event allows the public to discover or rediscover the country's architectural and historical treasures, which are often inaccessible the rest of the year.
For this new edition, more than 1,500 locations will open their doors throughout the country. In the Île-de-France region, visitors will be able to enjoy a rich program, with a special focus on the most iconic castles in the Paris area. It is a unique opportunity for families and history enthusiasts to explore prestigious estates.
The organizers encourage participants to plan their visit in advance. Due to the high turnout expected, some historical sites require mandatory online booking. Detailed programs will soon be available on the event's official website to allow everyone to organize their itinerary.
These days are free for the majority of participating sites. They represent an ideal opportunity to promote local heritage and raise public awareness about the conservation of French monuments. Whether you are an art or architecture lover, or simply curious, this weekend promises wonderful cultural discoveries in the heart of the region.
