Simserhof, France
The Simserhof is an ouvrage of the Maginot Line, located near the community of Sierstal in the French département of Moselle and faces the German frontier. During the Battle of France in 1940, Simserhof supported its neighboring fortifications with covering artillery fire, with partial success. The entire project ran from 1929 to 1938. By 1934 the central utility plant (usine) was in place, along with ammunition lifts and the internal railway. In 1938 the anti-tank obstacles were complete. Final costs were 118 million francs (equivalent to €30 million).
