Hundreds of years of British history and intrigue wrapped up in a medley of ancient towers, forts and embattlements. Plus, the Queen had a pretty nice jewelery collection. For some fantastic insight on the Tower Complex, I recommend a computer game called Traitor's Gate, where as a secret agent you must infiltrate the tower's defenses by exploring its various compenents while piecing together several clues related to the tower's history. I don't recommend attempting this in real life, but the role-playing game does this WH List justice.
