This château in Seine-et-Marne turns the Night of Museums into a Night of Cookies for a delicious, culture-filled late-night event.

Have you heard of the Château de Rosa Bonheur? This museum houses the former studio and home of the artist Rosa Bonheur. Located in Thomery, in the Seine-et-Marne region, the château allows us to immerse ourselves in the world of the famous painter. Paintings, smocks, paints and palettes, sketches, notes, clothes, accessories, furniture, personal effects... It's all here, preserved in perfect condition since 1899. All of Rosa Bonheur's belongings are on display, bringing to life the rooms of this home-studio.

What if you took advantage of the 22nd edition of the Nuit des Musées to discover this art-filled château? On Saturday, May 23, 2026, head to Thomery: a very special evening awaits you in a place full of life and mystery...
