The Yeomen Warders have guarded the Crown Jewels since 1303. They are, contrary to popular belief, authentic. Every morning there is a Ceremony of the Keys, during which the key-keeper answers the soldier's question: "Stop! Who's coming?" replies: "Her Majesty's Key." The crown jewels are used during ceremonies such as the inaugural session of parliament. They are then worn by the queen. They leave the Tower for a day or two, then return to the vault. There are over 3000 precious stones of extraordinary purity there, all valuables have historical significance and are priceless.
