Designed by Gilles Clément, the garden is an integral part of the museum: a bushy garden, sheltered from the noise of the quai by a high glass fence, it stretches over 18,000m² and provides an impression of abundance for those strolling past (visitors to the museum, residents in the area, walkers).

A place of nature and culture, the garden is an "invitation to go on a journey": pathways, small hills, tracks paved with river stones, ponds conducive to meditation and dreaming...

169 trees and approximately thirty plant species have been brought together: oaks and maples on the north side, magnolias and cherry trees on the south side.

Thanks to its stilts construction, the garden passes underneath the museum, the belly of which is planted with grassy undergrowth: here visitors to the museums will find the ticket counters, on the outside.

The garden also encloses a théâtre de verdure that hosts shows, lectures and concerts in the open air.
