The mystery of the destruction of the Order of the Temple by order of Philip the Fair has not ceased to excite minds for almost seven centuries. But over the past twenty years, the problem associated with the destruction of this order has again begun to arouse special interest and has given rise to various interpretations, primarily regarding Gisors and his strange castle. Whose castle is this anyway? What role did the Templars play in Gisors? Do secrets still sleep in the dungeons of this ancient fortress? Jean Marcal answers all these questions very objectively. The results of his investigation may be surprising: perhaps the Templars, who are most often considered victims of dark intrigues, rather obediently carried out the papal policy of subjugating the world? And for what scandalous secret did they die? Nevertheless, one mystery remains absolutely unsolvable: the Templars, still considering themselves Christians, renounced Jesus. Why? Taking full account of historical sources, Jean Marcal tries to clarify this burning mystery, separating indisputable facts from hypotheses that are too often put forward without any basis.
