This is one of the Hauts-de-Seine department's most cherished heritage sites, which you can visit free of charge during the Journées du Patrimoine 2025. The Musée Albert-Kahn and its gardens, housed in the former residence of banker and philanthropist Albert Kahn in Boulogne-Billancourt, welcome us on Saturday September 20 and Sunday September 21, 2025. Built by landscape architect Achille Duchêne on a four-hectare site in Boulogne-Billancourt, the site is an architectural and landscaped gem.
The Musée Albert-Kahn and its garden, an exceptional green setting at the gateway to Paris
The Musée Albert Kahn, with its sublime gardens, is a must-see. Imagined as a scenic garden, this 4-hectare space features a magnificent Japanese garden and village, an English garden, a French garden and forests and meadows. A complete change of scenery. [Read more]
An opportunity to learn more about the place and Albert Kahn, a colorful character. He founded Les Archives de la Planète, a company responsible for immortalizing the world's jewels in autochrome (the first color photographs). Albert Kahn was also passionate about plants. He therefore wanted to create a garden open to the public, showcasing every garden style in the world. In all, 6 gardens provide an exhaustive presentation of the art of gardening: a French garden, a Japanese garden with its tea pavilion, an English garden, a Vosges forest, a blue forest with its central marsh and a golden forest with its birch trees.
When it went bankrupt in 1932, the residence was seized, but was soon bought by the Prefecture of the Seine, which wished to continue welcoming the public to the gardens. The mansion was then converted into a museum, to display a fine selection of the 72,000 autochromes and thousands of hours of film produced by the ten photographers hired by Albert Kahn.
Explore the museum's landscape garden with a mediator and a gardener using the Pl@ntnet application.
Discover how Albert Kahn designed his garden, and how today, in the face of climate change, the garden must combine historical conservation with environmental preservation.
