"The Siege of Leningrad, also known as The Leningrad Blockade was an unsuccessful military operation by the Axis (Nazi) powers to capture Leningrad (now Saint Petersburg) during World War II. The siege lasted from September 9, 1941, to January 27, 1944, when a narrow land corridor to the city was established by the Soviets. The total lifting of the siege occurred on January 27, 1944. The Siege of Leningrad was one of the longest and most destructive sieges of major cities in modern history and it was the second most costly." - from Wikipedia. During nine hundred (!) days a few million people city of Leningrad suffered from cold and hunger, being deprived of almost all supplies of food and fuel. Many thousands died, those who
survived remember this not very willingly. The situation with food was so heavy, no food was sold/distributed among people except a few grams (not even tens or hundred grams) of bread, and not each day, that people had to eat stuff that they would never eat in normal life, like making soups of leather boots (because leather is of animal origin) or boiling the wallpaper because the glue with which they were attached to walls contained a bit of organic stuff. Of course many occasions of cannibalism occurred. On those photos you can see some pieces of those old photos made during those black days overlaid to the modern city views, respecting the place and angle of view.
