The Ghost Tour in Edinburgh is one of the most interesting activities. I went to the tour with my friends and I had been told that I would be scared to death. When we arrived, the tour guide was waiting for us. He told us a story. 200 hundred yeas ago, the medical science in Edinburgh developed very fast and people did a lot of research and experiment on the corpse. So the corpses were in great demand. As a result, a lot of fresh corpses were stolen from the tomb after they were buried shortly. Therefore, people had to use a metal cage to lock the tomb.
