Many mysterious things are hidden in the womb of the earth. When man reaches those things, surprising revelations occur. Something similar happened in the Italian city of Maples. A man was checking the mines near his house when he saw a door. When we gathered a lot of courage and went inside, the sight was astonishing. The ‘treasure’ was hidden 150 meters below the ground. A treasure, thanks to which their fortunes brightened and people got a chance to see a new world.
