Open 363 days a year, the site is constantly changing thanks to the International Garden Festival, which each year invites landscape architects and designers from around the world to submit projects combining creativity, poetry, and nature. At the end of the competition, experimental gardens are created which, together with the “Green Cards” offered to guests, completely transform the visitor experience at the estate.
In 2024, the theme of this laboratory of contemporary garden design was “Garden, Source of Life,” attracting a diverse audience: French and foreign visitors, experts and amateurs of all ages gathered at this site, which offers many other attractions. In 2025, the theme “Once Upon a Time in the Garden” guided the designers' work. Their creations had to take into account ecological constraints and enhance the presence of plants in their plots (2 guidelines for all editions of the Festival) while immersing visitors in the magical atmosphere of fairy tales.
