Set aside from urban life, the museum's park, with its shaded alleyways, rippling brooks, and trellises, has held onto the charm of the artist's "secret garden."

In 2004, it was recognized as a "Remarkable Garden," an award recently created by the Ministry of Culture and Communication. This label recognizes the garden's quality and charm, whose richness stems as much from its 17th and 18th century origins as from the modifications made by Ernest Hébert and his wife Gabrielle. The juxtaposition of well groomed, Italian style areas with English garden-type landscapes, the antique elements, and the numerous water basins are reminiscent of the Villa Medicis in Rome and make for an original setting, open freely to the public.
