Franz. Schaft 34cm Doppelgeschütz is a coastal artillery bunker located in France, part of the extensive Atlantic Wall fortifications built by Nazi Germany during World War II. This structure housed a 34cm twin gun battery, designed to defend the French coastline against Allied naval forces.
The bunker exemplifies the robust concrete construction typical of German military engineering in occupied territories, with thick walls engineered to withstand bombardment while housing heavy artillery pieces.
