The Casemate de Hatten Sud is a fortified bunker located in the Alsace region of northeastern France. It was part of France's pre-World War II defensive infrastructure, likely constructed as part of the Maginot Line system or similar fortifications designed to protect against potential German invasion. The area around Hatten saw significant military action during the war, particularly during the Battle of Hatten in January 1945, when Allied and German forces clashed in this sector of Alsace.
The casemate has been preserved and is now part of the Shelter Museum in Hatten, which showcases military equipment and artifacts from 1939 to the present day. The museum includes a restored casemate that sustained heavy damage during the German invasion, offering visitors insight into the region's military history and the experiences of local populations during the conflict.
