In memory and remembrance of the many victims of the last major German offensive in the West, known as “Unternehmen NORDWIND”, 75 years ago, 18 fortifications on both sides of the border between the Saar and Rhine opened their doors on the weekend of 11 and 12 January 2020. 22 different events commemorated the warlike events of January 1945, including exhibitions, lectures, a historical tour with US vehicles and a “Battlefield Tour”. The response in Baden, Alsace, Bitscher Land and the Palatinate was overwhelming with a total of over 2,200 visitors and many press articles. The cross-border commemorative weekend brought together fortifications and partners between the Saar and Rhine rivers for the first time in this form and laid the foundations for further co-operations and closer networking between the players involved in the shared cultural heritage of “fortresses”.
