Val-d'Oise is one of the 93 departments of metropolitan France, located in the
Île-de-France region. The department was created in 1968 following the division of the Seine-et-Oise department. The department is named after the Oise River, which flows through the province from northeast to southwest and is a right tributary of the River Seine. The Pays de France, an area of fertile plain traditionally used for agriculture, particularly cereals and sugar beet, is situated in the eastern part of the department, based on its fine, silty soils. The size of this region is continuously decreasing as Paris expands. Hauts-de-Seine lies to the south of the department, Yvelines to the southwest, Eure to the west, Oise to the north, Seine-et-Marne to the east, and Seine-Saint-Denis to the southeast.

Cergy-Pontoise: The New Administrative Capital
Although the official
préfecture of the department is Pontoise, located in the suburbs of
Paris, about 28 kilometres northwest of the city centre, the préfecture building and administrative offices are located in the neighbouring commune of Cergy. Cergy-Pontoise is the new administrative capital, created from 13 communes, which has quadrupled in population since the 1960s.
Charles de Gaulle Airport: A Key Landmark
The department is home to Charles de Gaulle Airport, which is partially situated in Roissy-en-France, a commune in the Val-d'Oise department. Other parts of the airport are located in the departments of Seine-et-Marne and Seine-Saint-Denis. The southernmost part of the department constitutes the Seine Valley and covers the entire
Vallée de Montmorency.
Cultural and Historical Heritage
Val-d'Oise boasts a rich archaeological and historical heritage, but it is not a tourist destination often visited, perhaps overshadowed by the French capital. However, the department has several interesting places to visit, including La Roche-Guyon. This place features a
castle atop a rocky hill and a twelfth-century château. L'Isle-Adam is another historic small town in the department, situated on the banks of the River Oise.
Impressionist Legacy in Auvers-sur-Oise
Auvers-sur-Oise owes its international fame to its landscapes and the impressionist painters who immortalised them, including Charles-François Daubigny, Paul Cézanne, Jean-Baptiste-Camille Corot, Camille Pissarro, and Vincent van Gogh. Enghien-les-Bains is a spa resort with a hot, sulfuric spring on the site of what was once Lake Enghien. Écouen features a fine château that houses the Musée de la Renaissance.
