Westwall bunker ruins in Naturpark Hohes Venn-Eifel

Between 1937 and 1940, the so-called West Wall was built along the West German border by order of the National Socialist regime. After the war ended, most of the structures were blown up and covered with earth. Here you can still see the remains of a former bunker.

Presumably, the term Westwall became increasingly common from the end of 1938, without the National Socialist propaganda initially using the term to any particular extent. He probably comes from the group of workers involved in the construction. In the second half of 1938, terms such as “Todt Line” (apparently the most common name, see below), “Schutzwall” or “Limes Program” were still used, while military circles popularized names such as “Führer Line” or “Hitler Line” wanted to.

The Siegfried Line was a military defense system spread over about 630 km along the western border of the German Empire, which consisted of over 18,000 bunkers, tunnels and countless trenches and anti-tank barriers. It ran from Kleve on the Dutch border in a southerly direction to Grenzach-Wyhlen on the Swiss border. Source: Wikipedia
