  ABSTRACT: In this article a construction of the Atlantic Wall discovered on 02/01/2006 near the Pointe Saint Mathieu (Finistère, France) is identified and its purpose is clarified. It witnessed the presence, during the World War II, at Pointe Saint-Mathieu, of a Kieswerk or pebble factory in which the pebbles and/or crushed pebbles of the Ero Vili were stored and distributed. The Kieswerk was very likely to have participated in the construction of the Atlantic Wall fortifications of the Pointe Saint-Mathieu.
