In 1946 Noël Corbu purchased the former estate of the Abbé Bérenger Saunière, comprising of the Villa Béthanie and the Tour Magdala, constructed by the former priest of Rennes-le-Château between 1900-1902. During Easter 1955 Corbu opened a restaurant in the Villa Bethania, that later during the 1990s was also turned into a Hotel.
Between 12th and 14 January 1956, the local newspaper, La Dépêche du Midi serialised an interview with Corbu and his brother Charles in which it was claimed that Father Saunière had discovered the treasure of Blanche of Castile the wife of Louis VIII and the regent of the future Saint Louis. Noël Corbu claimed that Abbé Bérenger Saunière had in 1892 discovered whilst renovating his church parchments “inscribed in a mixture of French and Latin, in which at first glance could be discerned passages from the Gospels”. It has been noted by critics that Saunière began renovating his church in 1886, not 1892, and that “there was no evidence that these parchments had ever existed”.
