A military bunker located near the coast of Brittany, France, this structure is part of the extensive Atlantic Wall fortifications built during World War II. The Vf Munition designation suggests it was designed for ammunition storage, likely supporting nearby coastal defense batteries. Situated in the Côtes-d'Armor department, this bunker exemplifies the German military engineering efforts along the French coastline during the occupation period.
The region around Saint-Brieuc and the northern Breton coast saw significant fortification construction as part of Nazi Germany's defensive strategy against potential Allied invasion.
