Good day to everyone and good mood! Dear like-minded people, I decided to create a topic and I hope that it will be interesting. I invite everyone to take part in the study, identifying the images of occupied Europe. I love riddles and the process of solving them.I hope you are too. So, a German soldier took a photo,he did not make an inscription on it.Thus, he created a kind of riddle for us, collectors and researchers.Where was the photo taken, in what place, in what period?This is where our task begins to solve the mystery of photography. You see, it’s interesting to learn more about photography, so to speak, to look beyond its scope, besides, it also broadens one's horizons. This is our task, otherwise the photo will remain impersonal and not very interesting. Let's all together try to solve these riddles, as well as virtually travel through the countries of the once occupied Europe. I want to warn you that there will be many riddles and the topic promises to be interesting. So, let's begin. The first photo:What is the cathedral in the photo,in which city?
