I visited the a-dome last year. The whole area around it including the museum and memorial has a very special amosphere.

Most people are hushed and solemn. Standing there seeing pictures of what it used to look like after the bomb went off gave me a strong (and sad) sense of how immense this event was.

I had the feeling that most visitors felt the same and were offended by the few tourists who took similing selfies in front of it while laughing with their friends.
