Parc naturel régional du Vexin français

The Parc naturel régional du Vexin français is a protected area situated on a limestone plateau between the Seine and Oise rivers. The landscape contains marshes, gentle hills, and forests that together form a varied patchwork of natural habitats.

The region takes its name from the Veliocasses, an ancient Gaulish people who inhabited this area. In 911, the Treaty of Saint-Clair-sur-Epte divided these lands between Norman and French territories.

Scattered throughout the park are castles, churches, and farmsteads that tell the story of rural life in this region. You will also encounter old mills, fountains, and communal washing areas that reveal how people lived and worked in past centuries.

The Maison du Parc visitor center in Théméricourt offers information and displays to help you understand the park's layout and features. This is a good starting point before exploring the different areas on foot or by bicycle.

In 2014, this park received the 'Pays d'art et d'histoire' designation from France's Ministry of Culture as the first regional park to earn this honor. The recognition highlights how natural landscape and cultural heritage are deeply intertwined here.
