Economy
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 associated TGV station provides access by rail to all parts of France. The department has nine business zones designated for high-tech industries.

Tourism
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; Royaumont Abbey, founded by St. Louis in the thirteenth century, is another important site. There are two protected nature areas in the department: the Parc naturel régional du Vexin français and the Parc naturel régional Oise-Pays de France.
Argenteuil is a sub-prefecture and is the second most populous of Paris' suburbs. It is in a scenic location by the River Seine and has been much-painted by Claude Monet, Eugène Delacroix, Pierre-Auguste Renoir, Gustave Caillebotte, Alfred Sisley and Georges Braque. It has several historic buildings and a local museum.
