The Tower of London is a two-volume history of famous British castle written by Lord Ronald Gower, a British sculptor and author. The Tower of London, officially Her Majesty's Royal Palace and Fortress of the Tower of London, is a historic castle on the north bank of the River Thames in central London. The Tower has played a prominent role in English history. It was besieged several times, and controlling it has been important to controlling the country.
