Rennes-le-Château is a castle in small hilltop village in Southern France that is at the center of many conspiracy theories. This summer I went there to explore the mysteries there. The stories told about Rennes-le-Château and Bérenger Saunière consist of many theories, revolving around all matters of conspiracies involving the Blanche of Castile, the Merovingians, the Knights Templar, the Cathars, and later, the Priory of Sion, the Holy Grail, Mary Magdalene, and the remains of Jesus Christ.
