CHÂTEAU DE SEPT-SAULX, UN CHÂTEAU EN CHAMPAGNE-ARDENNE
The History of the Château
A family story
Commissioned in 1928 and completed in 1930, the Château de Sept-Saulx was the property of Édouard Mignot, a prominent Champagne industrialist. Louis Süe, a Prix de Rome laureate, was its architect, Richard Desvallières crafted the ironwork, and Jean-Claude Nicolas Forestier—creator of the Bagatelle gardens—designed the French-style gardens.
Today, the château remains in the hands of Édouard Mignot’s heirs and is now open to the public for hosting unforgettable events.

The Château de Sept-Saulx was built by the architect Louis Süe at the end of the 1920s, at the request of Edouard Mignot, founder of the Comptoirs Français and owner of Heidsieck Monopole champagne.
Richard Desvallières executed the ironwork and the French gardens were designed by Jean Claude Forestier, who had already created the rose garden at Bagatelle.
The castle and its park are listed as historical monuments of France.
The castle was recognised as an exceptional 20th century monument in 2011. It was at this time that Marie-Sybille de Villaines Mignot had a chapel built to complete the work of her father-in-law. The Oratory is placed in front of the castle, in a predestined space located at the end of the pedestrian path that the guests of Edouard Mignot once took, arriving by the railway line.
Opening the château to hosting events of all kinds.
The story of Château de Sept-Saulx and my own are deeply intertwined. As the heir to this historic estate, I have always been committed to preserving its legacy while infusing it with new energy.
In 2020, I made the decision to open the château to events, driven by a desire to share this exceptional heritage. Initially approached for private receptions and film shoots, I quickly realized the unique appeal of this setting for event organizers, whether individuals or professionals.
In 2022, M6 contacted me to film the finale of Le Meilleur Boulanger de France. Enthusiastic about showcasing the château through a major national production, I seized this opportunity, which enhanced the venue’s visibility and confirmed its potential in the event industry.
Today, the Château de Sept-Saulx is an extraordinary setting where weddings, seminars, receptions, and film shoots come to life. Each event held here benefits from an elegant atmosphere and a tailored approach, reflecting the high standards and sophistication that define this place.
My goal is to continue writing this story by allowing others to experience unforgettable moments at the Château de Sept-Saulx.
