Château de la Forêt in Livry-Gargan exemplifies 19th-century Louis XIII style architecture, built in 1864 for Dr. Lefèvre on land formerly part of the legendary Bondy forest. Constructed with alternating brick and dressed stone, the château sits at the center of the ten-hectare Parc Lefèvre, offering a picturesque forest setting within the Île-de-France region. The castle now houses two municipal museums: the local history museum presenting artifacts and documents tracing Livry-Gargan's past, and the Sévigné museum dedicated to the 17th-century literary figure the Marquise de Sévigné. The venue regularly hosts temporary exhibitions of plastic arts including painting, sculpture, and photography, making it an educational destination blending cultural heritage with natural woodland surroundings.
