The Boulonnais (French pronunciation: [bu.lɔ.nɛ]) is a coastal area of northern France,[1] around Calais and Boulogne-sur-Mer. It has a curved belt of chalk downs which run into the sea at both ends, and geologically is the east end of the Weald-Artois Anticline.[2]
The Pays Boulonnais is subdivided into 3 intercommunalities: the Communauté d'agglomération du Boulonnais, the Communauté de communes de la Terre des Deux Caps & the Communauté de communes de Desvres - Samer.
