10 largest cities in France




Marne-la-Vallée is a new French town located east of Paris, in the Île-de-France region, on the left (south) bank of the Marne.

The new city developed from the 1960s, when the first master plan for land use planning and town planning (SDAU) was developed, entrusted to Paul Delouvrier, delegate general for the District of the Paris region from 1961 to 1969, which was therefore considered the father of new towns in France.

In 2016, it had a total of 316,171 inhabitants over 171.24 km2, for an average density of 1,846 inhabitants / km2. Relatively large, it stretches over twenty kilometers from west to east (from Bry-sur-Marne to Bailly-Romainvilliers), i.e. before the extension of the intervention perimeter of public development establishments carried out in 2017. First organized into four sectors, the different municipalities that make up Marne-la-Vallée then grouped together into different inter-municipal authorities (see the Composition section below).

Its inhabitants are called the Marnovallians.



In the 1960s, to cope with the rapid development of the Parisian agglomeration, it was decided to control its development by creating several new towns around Paris. The development of the first master plan for land use planning and development (SDAU) was entrusted to Paul Delouvrier, delegate general for the District of the Paris region from 1961 to 1969, who was therefore considered to be the father of new towns in France.

To the east of Paris, the choice of development fell on the valley of the south bank of the Marne made up of small villages and hamlets, very little urbanized at the time, and which therefore had large land reserves that were easily mobilized. . Unlike other new towns, such as Cergy-Pontoise or Saint-Quentin-en-Yvelines, Marne-la-Vallée will not be organized around a single urban center created from scratch, but rather around many urban centers, linked by the RER and the A4 motorway, the two major axes of the new town. This layout model is inspired by the new Swedish towns, built in the suburbs of Stockholm, and offers real advantages in terms of urban density and transport.

For practical and logical reasons, urbanization was decided from west to east, on the basis of four development sectors: Porte de Paris, Val Maubués, Val de Bussy, Val d'Europe. The oldest districts of the new city are therefore located in sectors 1 and 2 (Porte de Paris and Val Maubués) around the existing city centers. Their development is now almost complete. Sectors 3 and 4 are currently booming and in full urbanization.

Since the extension of Epamarne's scope of intervention, certain sectors of the new town have seen their names changed: sector 1 Porte de Paris has become Métropole du Grand Paris, Val Maubués is Paris-Vallée de la Marne, Val de Bussy is Marne-et-Gondoire.
