Buckingham Palace is where the Queen lives. It is the Queen’s official and main royal London home.
Buckingham Palace was originally a splendid house built by the Duke of Buckingham for his wife. George IV began changing it into a palace in 1826. It has been the official London home of Britain’s royal family since 1837. Buckingham Palace is also an office and used for the administrative work of the royal family.
When the Queen is at home you can see her royal flag flying from the flag pole on top of Buckingham Palace.
The flag is divided into four equal parts. The first and fourth parts represent England and contain three gold lions walking on a red field; the second part represents Scotland and contains a red lion standing on a gold field; the third part represents Ireland and contains the gold coat of arms of Ireland on a blue field.
In flag protocol(礼仪), the Royal Standard which must only be flown from buildings where the Queen is present is supreme(至高无上的). It flies above the British Union Flag, and other British flags. It never flies at half mast(降半旗)．
The guards of the Palace wear red jackets and tall furry hats. When the first guards come on duty, there is a ceremony called the Changing of the Guard. A familiar sight at Buckingham Palace is the Changing of the Guard ceremony that takes place in the open space in front of each morning.
