In Osny, in the Val-d'Oise, the château de Grouchy stands within a 42-hectare estate whose grounds are open to the public. Built in the late 18th century for the comte de Lameth and altered over the following century, this classical building was once home to the writer Edmond About and the banker Frédéric de Reiset. The château now houses Osny's town hall along with a firefighting museum and exhibition spaces, while the park still holds a temple d'Amour, an ice house and a pond edged by a walking path.
