Shortly after Hiroshima was hit by a nuclear bomb, Nagasaki was also hit. It was an alternative target, and was chosen because of poor visibility over the primary target. Nagasaki was virtually destroyed during WW I and now was destroyed again. Currently it gives the impression of a clean new city in a bowl surrounded by mountains and the ocean. The bomb was supposed to hit the train station and cause maximum human fatalities, but missed this target. The photos are mostly of memorials created to prevent such future events. As at Hiroshima the origami paper crane is the symbol of this wish for peace.
