William II, the Duke of Normandy and Conqueror of England built the Tower of London as a fortress and the White Tower was probable begun in the 1070s and completed in 1100.

After his conquest of England, William II became William I, King of England and the Duke of Normandy, removed the Saxon Noblemen, replaced them with Norman Lords and French became the official language of the English court for three hundred years.

This was the entrance to the Tower of London and a moat and drawbridge were positioned below.	This is the traitor's gate where enemies of the King of England were brought through for public executions and William Wallace, the patriot of Scotland, was brought through this gate to his execution for refusing to acknowledge the English rule of Scotland.
This is the Black Tower, named for the imprisonment, disappearance, and presumed murder of the two young sons of Edward IV, the twelve-year Edward V and 9-year-old Richard of Shrewsbury. The Duke of Gloucester, their uncle, declared them illegitimate (that did not seem to hurt William the Conqueror, who was also known as William the Bastard ) and was crowned King Richard III.	This castle is known as the White Tower, constructed under the authority of William the Conqueror and dates back over nine hundred years ago.
