Architecture is the great chronicle of humanity. The assumption that Gothic cathedrals are books on magic and alchemy in stone was put forward in the 19th century and has since been repeatedly confirmed by many prominent scientists and researchers. Anticipating the approach of global changes and trying to preserve for future generations sacred occult knowledge about the model of the Universe and the purpose of humanity, the Initiates were able to write down in stone information that could help humanity avoid death in a global cataclysm, which, according to ancient prophecies, should occur in this century. Jay Weidner and Vincent Bridges, having studied many early Christian, Kabbalistic and Gnostic written sources, including the legendary book of the mysterious Fulcanelli “Secrets of the Cathedrals”, as well as architectural monuments in different parts of the world, claim: the exact date of the Apocalypse can be found out if you find the key to ancient messages , encrypted in the ornaments and frescoes of Catholic cathedrals and buildings that have survived to this day.
