This story of treasures - material or spiritual - found at Rennes-le-Chateau and the fact that Christ had children by Mary Magdalene, regularly floats to the surface.
All intensified in the late 70's - early 80's. When 3 Media, Maclay Baygent, Richard Leigh and Henry Lincoln, wrote the book "The Holy Mystery," where they talked about the Abbe Saunière, who found the treasure Albigenses (or Templars or the Rosicrucians), and then move on to more and more bold hypotheses and finished his narrative Grail and the descendants of Christ and Mary Magdalene.
In my opinion, one of these journalists even filed a lawsuit against this dullard Dan Brown for plagiarism
I would only point out the inaccuracy:
Rennes-le-Chateau (Rennes-le Château) is located between Perpignan (Perpignan) and Carcassonne (Carcassonne), on the south-western border of France, Languedoc in the country, the cradle of the Albigensian or Cathar heresy (or religion), that is at the opposite end of to Lorraine (Lorraine), the eastern province from the main city of Nancy (Nancy).
The village of Arc, which was found a tombstone, headstone, reproduced in a painting by Poussin, located 10 km from Rennes-le-Chateau.
On the map, I noticed a large pink oval Lorraine, and small - Rennes-le-Chateau.
