The Château de By, otherwise the Musée de l'atelier Rosa Bonheur ("Museum of the Studio of Rosa Bonheur") is a museum run by a private owner, Katherine Brault, in the French department of Seine-et-Marne, on the edge of the Fontainebleau Forest. It is named after the former town of By, near Thomery. It was closed for refurbishment in 2016 but has since reopened by the Brault family in 2018.
