Plaine de France

The Pays de France, also called the Parisis or Plaine de France, is a natural region located in the Île-de-France administrative region to the north of Paris, France. It is essentially a silt plain devoted to cereal crops, of which the southern part is included in the northern suburbs of Paris and greatly urbanised, and also includes Charles de Gaulle Airport.

Administratively, the region corresponds approximately to the east of Val-d'Oise department, with part of Seine-Saint-Denis and the northeastern fringe of Seine-et-Marne.

The Pays de France is delimited in the south west by the Seine, in the west by the forests of Montmorency and Carnelle, in the east by the River Marne and the heights of Dammartin and Goële, and in the north by the Chantilly Forest and . It is bordered by the Vexin français to the west, by Brie to the east, by Multien and Goële to the north east, and by Valois and the Pays de Thelle to the north. To the south are Mantois, Hurepoix and the Pays d'Aulnoye. In modern times, the Parisian agglomeration has encroached on many of these traditionally defined areas and now makes up a new form of natural region.
