The attached picture is a replica from the most famous sculpture of Kathe Kollwitz, that you can see close to the Island Museum.
Kathe Kollwitz Museum is an intimate building adjacent to Charlottenburg Palace, with many impactful and unforgettable drawings and sculptures from Kathe Kollwitz. Impressive to see the evolution of her heart trying to express the pain and struggle of a mother who has lost a son during first world war. It's not the most well known museum in Berlin, but if it is worth the detour. If you visit Charlottenburg Palace, you should anticipate 45 minutes more to be mind blown by her legacy.
