La Coupole Bunker Complex

La Coupole, also known as the Coupole d'Helfaut-Wizernes, is a massive Second World War bunker complex located in the Pas-de-Calais department of northern France. Originally codenamed Bauvorhaben 21 or Schotterwerk Nordwest, this concrete structure was intended to serve as a launch facility for V-2 rockets targeting London and southern England. The site represents one of the most impressive examples of Nazi Germany's Atlantic Wall fortifications in France, showcasing the scale and ambition of their military engineering during the occupation.
