The Aschenbach casemate is one of 32 works of this type built in the Sundgau between 1936 and 1940 in order to reinforce the Maginot line. The Altkirch sector also had 7 artillery casemates with 2 pieces of 75 mm each (range 11 km). Their main mission was to prevent a possible enemy overflow by the Basel region and Swiss territory.

This reinforced concrete casemate has an armored observation bell, 2 47 mm anti-tank guns, 2 8 mm machine guns, 3 machine guns and 3 grenade launchers.
About 15 men occupied the structure, commanded by a lieutenant and 3 non-commissioned officers.
