La Coupole Bunker

La Coupole 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 dome structure was designed by Nazi Germany as a launch site for V-2 rockets targeting London and other Allied cities. The complex, situated about 5 kilometres from Saint-Omer, represents one of the most impressive examples of German military engineering from the war, featuring a distinctive dome structure that gives the site its name.
