A military bunker located near Saint-Louis, France, in the Alsace region close to the German border. This area saw significant fortification efforts during World War II, particularly as part of France's defensive preparations. The structure appears to be a gun emplacement with an attached shelter for the gun crew, typical of the defensive works constructed in this strategically important border region.
The Alsace area has a long history of military fortifications due to its position between France and Germany.
