Ouvrage Thonnelle, Military fortification in Thonnelle, France.
The fortification contains four combat blocks positioned along a ridge slope, featuring machine gun stations and observation points for defensive operations.
Construction started in 1935 at a cost of 23.7 million francs as part of the Maginot Line defenses, designed to protect France from potential invasions.
The garrison published a weekly newspaper called 'L'écho des blocs', managed by medical auxiliary Cauet, which documented life within the fortification.
The structure required three 75-horsepower SMIM generators to maintain operations and housed 189 military personnel during its active period.
The underground sections now serve as a sanctuary for bat colonies, while the surface structures remain visible in the surrounding landscape.
