Musée Gatien Bonnet

This museum shows the past of the city and houses works of neo-impressionist Lagny. It is situated on the Marne, in a mansion. The collection reflects the rich heritage of Lagny and the region. The ground floor is devoted to Archaeology (prehistoric collections come from major sites excavated in the last 20 years in the valley of the Marne), and local history. Upstairs is the section of Fine Arts, and temporary exhibitions.
