The Siegfried Line was a defense system stretching more than 630 km (390 mi) with more than 18,000 bunkers, tunnels and tank traps. It went from Kleve on the border with the Netherlands, along the western border of the old German Empire as far as the town of Weil am Rhein on the border to Switzerland. Adolf Hitler planned the line from 1936 and had it built between 1938 and 1940. In English,"Siegfried lin" commonly refers to this World War II defensive line opposite the French Maginot Line; the Germans called this the"Westwall"
