Why is the Tower of London Nicknamed the White Tower?
The White Tower is one building within the Tower of London. Everything within the outer walls is known as the Tower of London, and this includes The White Tower, the Bloody Tower and the Jewel House. Henry III had the exterior walls of the White Tower whitewashed in 1240, hence the name. The current white parts on the White Tower are made of Caen Stone, which is from France.
