Rennes-le-Château, a small village in France with a population of less than 100, was made famous by the village priest Bérenger Saunière.
A priest who grew up in poverty, but seemingly stumbled upon unbelievable wealth, so much so that he completely redecorated his church, as well as built himself a house with that money.
The origin of Saunière's money remains unknown to this day, though there are multiple theories - some more reliable than others - which has led to years of treasure hunters visiting the small French village.
