I've been to see both Les MisÚrables and Phantom of the Opera at the Opera/Theater. Much prefer the Phantom. I do not know how much reality there is to the Phantom but for the Chandelier falling at the Opera. A separate circumstance.
As for the reality behind the "Phantom himself? I doubt if there was a real man/phantom at all.
Also I know about Vatican City and Pitcairn Island. Both are interesting realities.
