Val-d’Oise

department, France

Quick Summary

Val-d'Oise is a department in the Île-de-France region of north-central France, located northwest of Paris. Its capital is Pontoise, situated on the Oise River. The department's name is derived from the historic region of Valois, which was historically part of the southeastern quarter of the modern Oise department and an adjacent portion of Aisne.123

Pontoise has a history dating back to its acquisition by Philip I in 1064 and played a role in the Hundred Years' War. Argenteuil, another town in Val-d'Oise, grew around a 7th-century convent and is known for the putative seamless robe of Christ. The department has experienced industrial development and suburban growth, becoming a commuter settlement due to its proximity to Paris.12
