There is a maze of huge underground tombs in Real District, central Paris.
The tunnel is over 300 kilometers long and 5 million bones are piled up in the walls and rooms.
Currently, access to the building is strictly restricted except for one of the 14 entrances.People believe there is an entrance to hell somewhere under the underground tomb.
A recent unauthorized intruder found something in the dark, threw a camcorder, screamed, and ran away, making headlines.
The camcorder contained an unknown shape and sound.Did he find the legend of Hell?
