The fort was designed to house a garrison of over 600 men during wartime operations.
It features a rare functioning internal electric railway system that once moved ammunition.
The fort's massive armor plating was specifically designed to withstand direct hits from 240mm heavy artillery shells.
Despite the surrender of France, the garrison at Schoenenbourg did not surrender until ordered to do so after the June 1940 armistice.
The complex includes a dedicated hospital block with an operating room that was never utilized for combat injuries.
The ventilation system included air filtration to protect against potential chemical gas attacks.
The fort is buried under approximately 20 to 30 meters of rock and earth for blast protection.
It is the most heavily armed fort on the northeastern section of the Maginot Line.
Fort Schoenenbourg is the largest open-to-the-public fortification of the Maginot Line in the Alsace region. It served as a major defensive bastion during World War II, firing more shells than any other fort in the sector. The structure consists of six combat blocks linked by a 30-meter-deep underground gallery system. Visitors can traverse over 2.5 kilometers of tunnels, including the command post, barracks, and an operating kitchen. The site remains largely in its original state, preserved as a historical museum. Its ventilation systems, ammunition lifts, and artillery turrets are still visible to guests. The fort was heavily damaged by German shelling in 1940 but held its ground until the armistice. It represents a significant example of 1930s French military engineering and defensive strategy.
