Over the years, it has been many things: an armory, treasury, menagerie, mint, public archive, and home of the Crown Jewels. For many years, it was also a jail where people such as Elizabeth I (before she was Queen), Lady Jane Grey, Anne Boleyn, and even 11 World War I German spies were kept, and where prisoners like Lady Jane Grey and Anne Boleyn were executed. Today, 6 crows live there which legend has will leave the tower one day and the the tower and monarchy will fall ... They have clipped wings now and there is always a guard who watches over them.
