Fort de Schoenenbourg (Fort Schoenenbourg) is located in the north of the Bas-Rhin department, near the border town of Wissembourg, between the municipalities of Hunspach and Ingolsheim. Due to its size it is the most extensive structure of the Maginot Line open to the public. The fort has two entrances made of reinforced concrete, but the rest of the structure is up to 30 m underground. There are subterranean barracks, kitchens, infirmary, central electrical, ventilation and air filtering systems, workshops, water and fuel reserves. Beneath the entrances there are six blocks, combat units with a facade pierced with firing slots for machine guns and anti-tank guns, and artillery blocks with collapsible, heavily armored turrets. The different parts are connected by tunnels equipped with an electric train on a 60 cm track. Beneath the staircases for the soldiers, there are six freight elevators from 1 to 5 tons.

Quite interesting is the complex electrical system of the fort, which is well lit and needs electricity for the operation of the turrets and other machinery. As a result, the fort uses numerous voltages, 20,000 volts, 3,000 volts, 440 volts, 220 volts, and even 110 volts DC. The technology, compared to a submarine put into the tunnel, required many specialists which ensured their proper functioning. That's the reason why almost a third of the men were technical staff. However, several parts of the system have aged and had to be replaced, the internal transformers in oil bath have been cleaned up and replaced by modern dry transformers which were placed outside. As this is probably the most popular site of the Maginot line, there were also additions for the safety of the visitors. This includes video surveillance, toilets, and a visitor counting system at the entrance to the fort which keeps track of entries and exits.
