The Vexin is a historical county of northwestern France. It covers a verdant plateau on the right bank of the Seine. The name of the Vexin is derived from a name for a Gaulish tribe now known as the Veliocasses that inhabited the area and made Rouen their most important city. The French Impressionist artists Monet and Van Gogh painted the wheat fields of Vexin and a regional nature park was established in the French Vexin in 1995.
