For Christmas this year me and my partner are planning a trip to Stuttgart / Black Forest area. We are both very interested in ww2. I'm trying to do my research to find the best attractions etc and one of things we want to see is german ww2 bunkers. However tourist sites etc don't list them. Does anyone know of any ww2 German bunkers that I can find in the Stuttgart / Black Forest area ? Google maps co-ordinates etc would be appreciated.
