<P> The Ravens of the Tower of London are a group of at least six captive ravens which live at the Tower of London . Their presence is traditionally believed to protect the Crown and the tower; a superstition holds that "if the Tower of London ravens are lost or fly away, the Crown will fall and Britain with it". Some historians, including the Tower's official historian believe the "tower's raven mythology is likely to be a Victorian flight of fantasy". </P> <P> Historically, wild ravens were common throughout Britain, even in towns, the tower being within their natural range . When they were exterminated from much of their traditional range, including London, they could only exist at the tower in captivity and with official support . They are tended to by an official Ravenmaster . Local legend puts the origin of the captive raven population at the time of King Charles II (reigned 1660--85). Some of the ravens at the tower were specially bred in Somerset . </P>
