GRONINGEN 23 December 2015, Today a picture of the plaque that commemorates the German capitulation in the former National Archives in Groningen on 16 April 1945. The capitulation was a blow in advance that began on April 13, 1945. During the fighting, the city of Groningen was devastated. I also made a picture of the plaque in the stairwell. For this I had to just ring the bell at a company that is located in the building. I was allowed to come in so that was a nice bonus.
