The White Tower built by William the Conqueror is the oldest and the most important building, surrounded by other towers, all having different names. One of the towers is called the Bloody Tower being as it is believed the scene of the murder of Edward V and his brother, the Duke of York. The Tower is guarded by the Yeomen Warders popularly called “beefeaters” (мясоеды). There are two letters, E.R., on the front of their tunics standing for the Queen’s name Elizabeth Regina. Their everyday uniform is black and red, but on state occasions they wear a ceremonial dress: fine red state uniforms with the golden and black stripes and the wide lace-collar, which were in fashion in the 16th century. Every night at 10 p.m. the Ceremony of the Keys or locking up the Tower for the night takes place. It goes back to the middle Ages. After the keys are carried to the Queen’s House where they are safe for the night, everyone who approaches the gate must give the password or he will be turned away.
