There are several theories about the contents of the Vatican Apostolic Archives: some theories claim that they contain secret information about the Priory of Sion, proof that Jesus had a wife and descendents, secret information about the third secret of the Fatima, the real Spear of Destiny, secret information about the Holy Grail and/or the Ark of the Covenant, a supposedly-real Chronovisor machine, and many other secrets. There are also theories that claim that the Vatican has information about the Illuminati, and even secretly contains the world's largest collection of porn.
