About the space
A rare blend of 19th-century grandeur and cutting-edge functionality, this multifunctional château offers a setting unlike any other. Built in 1886 and designed in the Art Nouveau style, it welcomes guests through a dramatic bridge suspended above a shimmering glass vault—once a lake, now transformed into a luminous underground conservatory. Beneath the geometric glass canopy lies the Grand Glasshouse, a 1,200 m² modular structure bathed in natural light, perfectly suited to large-scale conferences, showcases, and gala evenings.
Inside the main château, ornate Belle Époque salons await with gilded mouldings, chandeliers, and vibrant murals, ideal for strategy meetings, board retreats, or high-end client sessions. Two auditoriums—one seating 270, the other 40—are fully equipped for video projection, livestreams, and immersive presentations.
Breakout rooms for up to 19 participants provide quieter zones for focused work, while the terrace orangery and 7-hectare gardens set the stage for elegant receptions and team-building activities. Whether you're hosting a leadership summit, an international symposium, or a brand launch, this estate brings history and innovation into perfect harmony.
Located just 30 minutes west of Paris and set within a pioneering research and tech campus, it combines accessibility, inspiration, and world-class amenities in one exceptional destination.
