OB 2cm Flak is a military bunker located in southeastern France, near the Mediterranean coast. The designation 'OB' typically refers to 'Objekt' or 'Bunker' in German military terminology, suggesting this structure was part of the Atlantic Wall defensive system during World War II. The '2cm Flak' designation indicates it was designed to house anti-aircraft artillery with 2-centimeter caliber guns, likely for defending against low-flying aircraft.
This bunker represents the extensive fortification network built by Nazi Germany along the French coastline during the occupation period.
