Höckerlinie des Westwalls
The western wall was a 630 km long military fortification along the western border of the German Empire, which was planned and built between 1936 and 1940 by the National Socialist regime. It consisted of more than 17,000 concrete bunkers and several hundred kilometers of armored barriers. The fortification was stylized for the population by Nazi propaganda as an "invincible bulwark" against an impending French attack. In mid-December 1944, the West Wall was the starting point for the Ardennes offensive.
In the Großkampenberg, Leidenborn and Kesfeld areas, 115 bunkers and around 6 kilometers of cusp line were built. The highly visible cusp line shapes the image of the west wall up to the present day.
