Such legends continue to live (and in cycles) from primitive man. Many tales exist but no such place exists.Think of ancient "religions" where the gods and demons came from inner earth, hades, the river styx, etc., to do their mischief. Remember that you have to take information on the internet with several grains of salt. Anyone and everyone can espouse any crazy or absurd thought anywhere. The socalled expert sites have anything anyone wants to put on it.
