Lost Treasure of the ancient Catholic Church
When Pope Gregory XI abruptly decides to move the Papacy back to Rome in 1377, chaos and rebellion descends upon both Avignon and the Papal States in Italy. The Rome-based Pope's foes and critics are everywhere and any shipment of the papal treasury from Avignon to the Vatican is at risk. An ingenious location is devised by Sir Jean Termonde, a heroic knight, to secure the treasure from discovery until it can be transferred to Rome.
The papal treasure never arrived at the Vatican, and the legend of the lost gold and jewels has grown over the centuries.
