Its position south of the Forêt de Saint-Germain-en-Laye and west of Saint-Germain-en-Laye places it between transport axes such as the A13 autoroute, the D30 (Yvelines) departmental road, and the SNCF suburban rail networks serving Gare Saint-Lazare, Gare Montparnasse, and Gare de l'Est.

In the 19th century the expansion of Chemin de fer de l'Ouest and urban development tied the area to Napoleon III’s projects and to nearby Versailles court influences. The 20th century saw wartime occupations during World War I and World War II, liberation linked to operations near Île-de-France and postwar urban planning aligned with initiatives from Évry and the Grand Paris projects.
