Cergy

Cergy is an administrative unit in Val-d'Oise that runs along the Oise River, linking residential areas with office districts as well as schools and universities. The townscape shows modern architecture beside older village cores, interspersed with parks and open spaces along the banks.

The settlement remained a small farming village with a few hundred inhabitants until the second half of the 20th century. After a regional planning reform, it was rapidly expanded and now hosts important regional offices, even though a neighboring town officially remains the department capital.

The name Cergy comes from a Roman villa once called Cariciacum, named after its owner. Today, this Latin heritage appears on street signs and public buildings that deliberately reference the ancient origin of the settlement.

Several regional train stations connect the town to Paris and the airport, with the journey to the capital center taking around 40 minutes. Local bus lines run between different town districts and neighboring communes, making it easier to explore without a car.

The Port Cergy marina sits directly beside the new town and offers moorings for leisure boats on an artificial body of water. On summer evenings, local residents gather on the waterside terraces to watch the late sun over the low hills.
