The â€œGenbaku domeâ€ was the closest building to the Hiroshima bomb's ground zero to keep standing after the blast. The explosion epicenter was only 150 meters from this building. All the surrounding constructions were blasted away and only these walls were still standing.
For the most part, the building is ruined, but the authorities wanted it to stay that way as a museum to commemorate the horror. In this panoramic view, we can visit it without going to Japan.
