This Hiroshima Peace Archive is in Pinghe Park. It is free of charge. I don't know why Trip.com wrote tickets. On the side is the very famous Pinghe Monument. This is a two-story building. There is a lot of space inside. There are a lot of people who come to visit. Many are foreigners in tour groups. The information inside is also good. It is suitable for understanding the destructive power of war, but the only bad thing is that the closing time here is earlier. If you are late, there is no way to visit.
