Ruins are fascinating. They provide enough detail to see how the ancient world lived, but still allow you to use your imagination to fill in the blanks.
The thing is, though, that most people never visit them because they are scary as anything. They could collapse at any moment, or there might be some monster lurking there. It is easy to understand why some people would never want to go there.
Fortunately, you don't need to. You can just read about other people's experiences and learn that they are exactly as scary as you imagined.
