The conspiracy theorists believe there could be a “tomb of Jesus Christ” in Septimania.
Christian Doumergue wrote something similar to this in one of his books, but he was unable to provide the slightest shred of historical evidence.
The legend of Mary Magdalene fleeing to France after the Crucifixion was only first mentioned by Sigebert of Gembloux who lived during the late 11th and early 12th century. His account (Chronicon ab anno 381 ad 1113) was first published in Latin in 1513. The bit about Jesus Christ going with her was a later addition.
