A palace and a prison.
The Tower of London, officially "Her Majesty's Royal Palace and Fortress", is a historic castle on the River Thames, founded by William the Conqueror in 1066 to assert Norman power, evolving from a formidable fortress and royal residence into a notorious prison, treasury, and royal zoo, famous for its iconic White Tower, Crown Jewels, Yeoman Warders, and tales of intrigue, betrayal, and royal executions like Anne Boleyn.
