context_page_description: The Siegfried Line, known in German as the Westwall, was a German defensive line built during the 1930s opposite the French Maginot Line. It stretched more than 630 km; from Kleve on the border with the Netherlands, along the western border of the old German Empire, to the town of Weil am Rhein on the border to Switzerland – and featured more than 18,000 bunkers, tunnels and tank traps.
  From September 1944 to March 1945 the Siegfried Line was subjected to a large-scale Allied offensive.
