The OB 2cm Flak bunker is a World War II German defensive structure located in Normandy, France. This type of bunker was designed to house anti-aircraft artillery, specifically 2cm Flak guns, as part of the Atlantic Wall fortifications. The bunker's position near the coast would have been strategic for defending against Allied air attacks during the D-Day invasion and subsequent operations in 1944.
The concrete structure exemplifies the military engineering of the era, built to withstand bombardment while providing protection for the gun crew and ammunition.
