Westwall, Siegfriedlinie, Hockerlinie

All names for the German defense line in WO II.

The Westwall (or Siegfried Line at the Allies) was a German defense line built before and during the Second World War and runs from Kleef, on the Dutch border, to the Swiss border. The Westwall has a length of more than 630 km. The Westwall was a consortium of (underground) bunkers (also called pill boxes), concrete tank bugs (also known as dragon teeth), track rails, barbed wire barriers and minefields.

In the years before the Second World War many European states built their own defense lines. That's why the Germans built a defense line in the east and west of Germany. Namely referred to as Ostwall and Westwall.

The Westwall was built between 1936 and 1945 on behalf of Adolf Hitler. The management of the works was entrusted to engineer Fritz Todt. The west west (Westwall) was a response to the French Maginot line, a giant fortress system along the German border, which forced the Germans into awe.
