Ouvrage Laudrefang, Military fortification in Moselle, France
Ouvrage Laudrefang is an underground military fortification in Moselle with five combat blocks connected by galleries that extend across multiple levels approximately 30 meters (100 feet) deep. The complex houses barracks, ammunition storage, a power plant, kitchen, and medical facilities designed to support extended occupation by troops.
The fortification was built in 1931 as part of the Maginot Line to defend the French border. In June 1940 it endured heavy German artillery bombardment before the French surrender ended the combat.
The structure represents French military engineering of the 1930s, demonstrating the national focus on territorial defense through permanent fortifications.
Access is through an opening at the top of the hill that leads down into the underground chambers. Visitors should be ready for narrow spaces and changing light levels, as interior areas are only partially lit.
Block 3 stands apart from the others and was equipped with twin machine guns and mortar embrasures, making it a critical defensive position. This isolated location allowed defenders to engage attackers from multiple angles.
