Here comes the must-attend date for budding explorers! The Heritage Days await you each year on the third weekend of September to immerse you in a wealth of exciting discoveries. At every edition, we are invited to enjoy free tours, 'unusual activities and exceptional openings aimed at revealing our heritage from every angle.
In Paris and the Île-de-France region, numerous monuments and other fascinating spots are in the spotlight. From museums, embassies, churches, ministries, fashion houses,temples of craftsmanship, and much more, the Île-de-France region invites us on a treasure hunt, with so many options that it’s hard not to find outings that fit your passions.
The upcoming and 43rd edition is set to return on the weekend of 19 and 20 September 2026. And perhaps this time we should head to discover the Castles of Île-de-France? In particular, in Seine-et-Marne, the Château de Brie-Comte-Robert is unveiling its Heritage Days program. This fortress, a medieval relic, was erected in the 12th century. Partially destroyed over its history, the site now listed as a historic monument continues to be the subject of archaeological digs. The Château de Brie-Comte-Robert still has more of its story to tell and may well harbor more secrets.

Conference: Stone carving in the modern world
### Stone carving in the modern world
Timothé Cayre
It is with immense pride and satisfaction that we invite you to this exceptional conference, part of Heritage Days.
We are honored to welcome Timothé Cayre, a flagship figure of our association whose journey is a genuine source of inspiration.
He began his path as a volunteer stone carver with our association, Les Amis du Vieux Château. He has turned his vocation into real expertise.
After deepening his engagement as a civic service member and then as staff, he left the organization, only to return with renewed energy.
He trained, earned his qualifications, and became a professional stone carver. Beyond his core duties, he now leads the stone-carving workshops and oversees the volunteer projects at the château.
He presents his topic of study: Stone carving in the modern world. A reflection on the stakes of using materials often treated as belonging to the "old world."

Round table: why and how to integrate contemporary buildings into a listed historic monument? The case of the Château de Brie-Comte-Robert
### Round Table
Sophie Vatin, architect
A tribute to Jean-Claude SÉMON, her collaborator.
Why and how to integrate contemporary architecture into a listed historic monument?
We have the honor of welcoming architect Sophie VATIN for a cross-disciplinary reflection on the philosophy and the choices that govern integrating and building the contemporary within a listed monument.
Sophie VATIN, the architect who, with Jean-Claude SÉMON, helped advance the château's enhancement project. Under their leadership and in collaboration with the association The Friends of Brie-Comte-Robert's Old Castle, the CIP and the archaeological base were conceived and built.
Through this round table, Sophie will illuminate the decisions that allow historic architecture to embrace contemporary creation.
Together, we will contribute to this discussion.
