Cergy

The commune of Cergy extends along the Oise River, encompassing residential neighborhoods, commercial districts, and educational facilities across 11.2 square kilometers.

Initially a rural settlement with under 3,000 residents in 1968, Cergy transformed into an administrative hub following the reorganization of the Paris region departments.

The Port Cergy marina includes waterfront restaurants, recreational spaces, and residential areas where residents gather for seasonal community events throughout the year.

Three RER stations connect Cergy to central Paris within 40 minutes, while local bus networks provide transportation to Charles de Gaulle Airport and surrounding communes.

The prefecture building, despite Pontoise being the official capital of Val-d'Oise, operates from Cergy, making it the functional administrative center of the department.
