Hiroshima Peace Park and Atomic Bomb Dome, Japan

Hiroshima in Japan - the site of the world’s first atomic bombing - isn’t exactly the first destination on a traveller’s list for a cheerful holiday. But it sure is moving.
The spot where the first atomic bomb used in warfare exploded is now known as the Hiroshima Peace Park, with the most striking sight being the Atomic Bomb Dome. This was a former exhibition hall, and it has been deliberately left as a ravaged shell to remind visitors of the destruction wreaked.
Also in the park is the Hiroshima Peace Memorial Museum, which goes into depth about the horrors of the atomic bomb and the effect it had on the city.
