The Centre-ville is the historic heart of Lagny-sur-Marne, on the banks of the Marne. An abbey town and a fair town, it has kept a tight medieval street plan around the abbey church of Notre-Dame-des-Ardents and the town hall. It is organised around the place Marchande, the place de la Fontaine and the place de l'Hôtel-de-Ville, the rue Gambetta, the rue d'Orgemont, the rue Jeanne-d'Arc, the rue du Château-Fort, the rue des Tanneurs and the rue du Chemin-de-Fer. The town council calls it « Cœur de ville ».
The abbey church, built in the thirteenth century in the Champagne Gothic style, has been listed as a historic monument since 1886. The town hall has occupied the buildings of the former abbey since 1842; its seventeenth-century façade has been on the supplementary inventory of historic monuments since 1969. The Joffre and Maunoury bridges cross the Marne to the north bank, where Lagny - Thorigny station stands.

The district attracts buyers who want to live on foot, close to the shops and the market on the place Marchande, the quays of the Marne and the bridges leading to Lagny - Thorigny station: working people, couples, retirees, and investors aiming to rent out small units.
