The original Siegfrie line (Siegfriedstellung) was a line of defensive forts and tank defenses built by Germany as a section of the Hindenburg Line 1916-1917 in northern France during World War I. However, in English, Siegfried line more commonly refers to the similar World War II defensive line, built during the 1930s, opposite the French Maginot Line, which served a corresponding purpose. The Germans themselves called this the Westwall, but the Allies renamed it after the First World War line. This article deals with this second Siegfried line.
