Although today the Tower of London is a famous tourist attraction, in the past it was a fortress, a palace, a prison and even a place where money was made. Just after 1066, William the Conqueror ordered the construction of the main tower, which came to be known as the White Tower after it was whitewashed in 1241. A famous part of the Tower of London is the Traitor’s Gate, through which those who had upset the Kings and Queens of England were brought to the Tower. Later, prisoners would be taken from their cells to be executed at Tower Green, inside the Tower’s walls. Do the ghosts of Henry VIII’s wives still walk these paths? Today the Tower is home to the famous black ravens, the Crown jewels and the Beefeaters in their colourful uniforms, all of them well-known symbols of England throughout the world. Every evening, at 10 p.m., tourists can watch the famous ceremony of the keys, when the tower is locked for the night.
