From Wikipedia, the free encyclopedia
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]
