The centre of Berck's maritime religious life, the Saint-Jean-Baptiste church has a square-based tower built in the 13th century which served as a watchtower and probably as a "coast light" or "foïer".
Originally, it ended in a terrace, and it was not topped by a bell tower until the 17th century. The tower is followed by a nave flanked by a single aisle which ends in a higher choir dating from the 16th century.
Its interior reveals a variety of styles which inform us about the various successive alterations. Its sixteen lamp-ends, listed as Historic Monuments, are remarkable. These are small supports that receive the fall of the arches or support sculptures.
