The Journées du Patrimoine (Heritage Days) is the major cultural event not to be missed in September. It's a flagship event for which the entire Paris region is delighted to lend its support. And with good reason: this cultural event invites us to explore our heritage from every angle over the course of a weekend. For this 42nd edition, reserve the dates of September 20 and 21.
To mark the occasion, a wide range of visits, often free of charge and accompanied by special events, await you in Paris and the Paris region. Museums, monuments, churches, libraries and even castles- many well-known and little-known treasures will be revealing their secrets on this occasion. Exceptional visits are also planned to places normally closed to the public, including ministries, embassies and major institutions.
It's the perfect time to explore the heritage of the Paris region, particularly in Seine-et-Marne, where heritage nuggets abound. In the 77 department, the town of Monceaux-le-Meaux boasts a fascinating historic site: the Château Royal de Montceaux, also known as the Château des Trois Reines.
Acquired in the 16th century by Catherine de Médicis, the estate later became the property of King Henri IV and was offered to Marie de Médicis on the birth of Louis XIII. It was destroyed shortly after the French Revolution, but many vestiges of this Seine-et-Marne heritage treasure remain.
