Between the fortified region of Metz and that of the Lauter, the Saar Gap stretches for some 40 kilometres and was annexed to Germany in 1935. This gap then became a potential "gateway" for the enemy. As early as 1927, studies were carried out to block this gap between the German Nied and the Saar river using a natural obstacle: water. Itinerary by car or motorbike, not recommended for cyclists.
