Ouvrage Rohrbach (or Fort Casso) is a petit ouvrage of the Maginot Line located in the community of Bettvillier, near Rohrbach-lès-Bitche in the Moselle département, facing Germany. The Fortified Sector of Rohrbach was built somewhat later than its neighbors to the east and west, and in company with positions on the extreme western end of the Maginot Line, became one of the "New Fronts."
