Buckingham Palace has been the official residence of the British monarch in London since 1837. The Palace is currently home to Queen Elizabeth II. Built in 1703 by the Duke of Buckingham, the building was acquired by King George III in 1762 to be used as a private residence. The Changing of the Guard takes place at the main entrance to Buckingham Palace throughout the whole year. The ceremony involves the changeover of the Guards, who are in charge of security at the Palace, and is accompanied by a military band.
