Fortification of Schoenenbourg is a Maginot Line fortification and it is located in Alsace, France Officially recorded as an historical monument, it retains all its original structural elements. Schoenenbourg was heavily bombarded during the Battle of France in 1940, receiving more enemy ordnance than any other position in France, with no significant damage. The work is composed of eight blocks, with six combat blocks including two casemate blocks, a personnel entrance block and an ammunition entrance block. A total of 3,000 metres of galleries extend between 18 metres and 30 metres below the surface In 1987 the French Army allowed Alsace Association of Friends of the Maginot Line to conduct tours of the fortification. From 1981 the group has worked to restore Schoenenbourg and today is open to public visitation.
