Lagny-sur-Marne
The Essential
Lagny-sur-Marne, a lively residential city, was originally a fortified town, the site of an abbey and an important international trading centre. Joan of Arc stayed here on numerous occasions, most famously in April 1430. Sights of interest include the 13C Notre-Dame-des-Ardents-et-Saint-Pierre church and the Gatien-Bonnet museum which includes a local history section and an art gallery with a good collection of Pointilliste works.
