BERCK, a bathing resort of northern France, in the department of Pas-de-Calais, 25 m. S. of Boulogne by rail. Pop. (1906) 7638. It comprises two parts—Berck-Ville, 112 m. from the shore, and Berck-Plage, the latter with a fine sandy beach. There are two children’s hospitals, the climate proving peculiarly beneficial in the treatment of scrofulous affections.
