Ouvrage Métrich, Maginot Line fortification in Kœnigsmacker, France
The military structure contains twelve combat blocks connected by underground galleries reaching depths of 30 meters below the surface to withstand bombardments.
Built between 1930 and 1935, Ouvrage Métrich became the third largest fortification of the Maginot Line after Hackenberg and Hochwald installations.
The fortification housed a garrison of 769 soldiers and 26 officers from the 167th Infantry Regiment and 151st Artillery Regiment during its operational period.
The fortress maintained autonomy through four electrical generators, supplemented by water reserves, fuel storage, food supplies, and ventilation systems.
The structure deteriorates due to its construction on anhydrite banks, causing internal damage to the galleries and military installations.
