The estate can be privatized for a day or for several days.
Seminars and company events
Professional events are sold through Domaines & événements, the group that has run the estate since 2014. Formats include residential seminars, meetings, training sessions, team building, afterwork events and company cocktails. Plenary sessions take place in the air-conditioned Grande Galerie, which seats up to 220. The estate counts six meeting rooms in all, plus several salons for breakout work, a large terrace and a 6-hectare park.

Spaces are available from 3 p.m. on the day, the evening ends at 4 a.m., and a brunch can be served the next day on the Grande Terrasse.

History and setting
The estate goes back to a fortified house, but the present château dates from the 18th century. The Marquis de Broglie sold it in 1778 to the Fayet family, who carried out major works from 1779 to 1794. The dovecote dates from 1781. The château was restored between 2021 and 2024, and a 2026 program added air conditioning to 10 bedrooms. The park has century-old trees, fountains and a kitchen garden.
