The ravens of the Tower of London are a group of at least six ravens. The group of six ravens is kept captive at the Tower itself. These Ravens are associated with the Tower and the Crown by a superstition. The superstition says that “if the Tower of London ravens are lost, or they fly away, the Crown will fall and so will Britain with it.” Specific Raven Masters feed these ravens. Today, the Tower of London plays host to seven Ravens (six as per the superstition and one as backup).
