Vauvert had never been haunted until then. But as soon as the monks of St. Bruno took up residence nearby, lights glowed in windows and the sounds of humans in misery echoed from it's rooms at night. Eventually, there were numerous reports of a giant, green, glowing specter standing in an upstairs window that would generally harass the passerby.

The King himself eventually sent a commission to investigate the palace. On arrival they interviewed the monks, who were shocked as well. The monks did, however, hint that if they were allowed to live in the palace, then the ghost would be forced to leave.

The King agreed to this and the haunting stopped abruptly forever. This case remains as one of the more successful paranormal hoaxes in history.
