The 2026 Heritage Days program at Domaine de la Reine Margot in Hauts-de-Seine (92)

The Heritage Days are the perfect opportunity to discover great cultural deals. This unmissable event arrives each year on the 3rd weekend of September. On this occasion, many venues—both public and private—join the party, inviting us in with a program of often free tours, unconventional activities, and exceptional openings. From must-see museums to hidden monuments, including churches, castles, ministries, embassies or even great institutions, Paris and Île-de-France come alive each year with a broad program that lets us explore the riches of our heritage in depth.

And the Hauts-de-Seine region is no exception. The department 92, tucked west of the capital, hops into the Heritage Days lineup with its own treasures, showcasing its historic and artistic gems. In the city of Issy-les-Moulineaux, the Domaine de la Reine Margot invites everyone to enjoy a special program for the 43rd edition scheduled for the weekend of September 20 and 21, 2025. Incidentally, the town also offers several guided tours of its monuments if you’d like to dig deeper into Issy-les-Moulineaux’s standout sites.

• Guided Tours of Domaine Reine Margot

  The Domaine Reine Margot marks the stay of the famed sovereign who, in 1606, became the first high-born aristocrat to establish a country residence in Issy. It has been redesigned into a prestige hotel ensemble by Jean-Michel Wilmotte, preserving its listed parts: a 17th-century building and a neo-Gothic chapel inaugurated in 1846.

  Paid mixology workshops are offered at the end of these visits (reservations: Alicia.WINDUST@accor.com). Audio guides are also available for a self-guided tour.
