First known article published in the press during Saunière's lifetime that mentions Rennes-le-Château as one of the great tourist excursions of the area. On September 13, 1913, an excellent article entitled "Les Bains de Rennes" was published in La Bataille Republicaine, a radical and socialist newspaper, which mentions many of the elements that involve the myth that we now know about Rennes-le-Château ... but this time without myth, in the best pure journalistic style of a travel magazine.
