Through a ruined cemetery filled with statues lies a tunnel that leads to an underground city. Its history is more terrifying than that of France’s worst revolutions.

As guests venture forth into the dank, dripping corridors of rat-infested remains, the voices of the dead begin to speak, and some have taken shape.
