Val-d'Oise (French:[valdwaz]ⓘ, "Vale of theOise") is adepartment in theÎle-de-Franceregion, Northern France. It was created in 1968 following the split of theSeine-et-Oise department. In 2019, Val-d'Oise had a population of 1,249,674.[4]
It is named after the riverOise, a major tributary of theSeine, which crosses the region after having started in Belgium and flowed through Northeastern France. Val-d'Oise is Île-de-France's northernmost department.Charles de Gaulle Airport, France's main international airport, is partially located inRoissy-en-France, a commune of Val-d'Oise.
The original departments of France were established in 1790 when the French National Assembly split the country into 83 departments of roughly the same size and population. They were designed as sets of communes, and when better maps became available, certain revisions had to be made. In 1964, it was determined to divide up the departments ofSeine andSeine-et-Oise. Val-d'Oise was one of the new departments so formed, and was created entirely from the previous department of Seine-et-Oise.[5]
Val-d'Oise is a department in north central France and is part of the region ofÎle-de-France. To the south of the department lies the department ofHauts-de-Seine, to the southwest liesYvelines, to the west liesEure, to the north liesOise, to the east liesSeine-et-Marne and to the southeast liesSeine-Saint-Denis.[6] The officialpréfecture (capital) of the department is the commune ofPontoise, situated in the suburbs ofParis some 28 kilometres (17 mi) northwest of the centre of the city, but thepréfecture building and administrative offices are in the neighbouring commune ofCergy. TheRiver Oise is a right tributary of theRiver Seine, and flows through the province from northeast to southwest.[6]
The eastern part of the department is part of thePays de France, an area of fertile plain traditionally used for agriculture (particularly cereals and sugar beet) based on its fine silty soils. This part is progressively diminishing in size as Paris expands. Part ofCharles de Gaulle Airport falls in this eastern region, while other parts are in the departments of Seine-et-Marne and Seine-Saint-Denis. The southernmost region of the department forms part of theSeine Valley and occupies the whole of the smallVallée de Montmorency. These parts are heavily urbanised, but the ancient Roman road, theChaussée Jules César, which linked Paris andRouen, passes through the latter. The central and southwestern parts of the department are also largely urbanised and part of the greater Paris sprawl. The western part of the department forms part of the historic county ofVexin français, a verdant, largely agricultural plateau. Its capital wasPontoise on the eastern extremity of the county. This commune is now combining with the neighbouring commune ofCergy to form the new town ofCergy-Pontoise. The Vexin area remains largely rural, and across the whole department, one fifth is covered with trees.[6]
The economy of Val-d'Oise relies on two different themes. The northern, eastern and western parts are fertile areas of agricultural land producing large quantities of corn, sugar beet, and other crops. The urban parts to the south are dormitory towns, used by people working in the greater metropolitan area of Paris. The presence of Charles de Gaulle Airport and its associatedTGV station provides access by rail to all parts of France. The department has nine business zones designated for high-tech industries.[7]
1 This group is made up largely of former French settlers, such aspieds-noirs inNorthwest Africa, followed by former colonial citizens who had French citizenship at birth (such as was often the case for the native elite in French colonies), as well as to a lesser extent foreign-born children of French expatriates. A foreign country is understood as a country not part of France in 1999, so a person born for example in 1950 in Algeria, when Algeria was an integral part of France, is nonetheless listed as a person born in a foreign country in French statistics.
2 An immigrant is a person born in a foreign country not having French citizenship at birth. An immigrant may have acquired French citizenship since moving to France, but is still considered an immigrant in French statistics. On the other hand, persons born in France with foreign citizenship (the children of immigrants) are not listed as immigrants.
The department has a rich archaeological and historical heritage, but is not a region visited much by tourists, perhaps being overshadowed by the French capital. Places of interest include the following sites;[13]La Roche-Guyon with a castle on top of a rocky hill and a twelfth century château;L'Isle-Adam, a historic small town on the bank of the River Oise;Auvers-sur-Oise, which owes its international fame to its landscapes and the impressionist painters such asCharles-François Daubigny,Paul Cézanne,Jean-Baptiste-Camille Corot,Camille Pissarro andVincent van Gogh who immortalised them;Enghien-les-Bains, a spa resort with a hot, sulphurous spring, on the site of what was originally Lake Enghien;Écouen with a fine château which houses the Museum of the Renaissance; Cergy-Pontoise, the new administrative capital which has been created out of thirteen communes and has quadrupled in population since the 1960s. There is a branch of the Académie de Versailles in the city which provides tertiary education;Théméricourt, where as well as a fine château, there is the historic church of Notre-Dame, and the twelfth or thirteenth century Croix de l'Ormeteau-Marie.[14]Royaumont Abbey, founded by St. Louis in the thirteenth century, is another important site. There are two protected nature areas in the department: theParc naturel régional du Vexin français and theParc naturel régional Oise-Pays de France.[13]
