Changing of the Guard, one of the top attractions in London!
The Changing the Guard ceremony, or Guard Mounting as it is formally known, signifies the official handover of responsibility for the military security of the Royal Palaces in London.
Household Troops have guarded the Sovereign and the Royal Palaces since 1660.
Until 1689, the Sovereign lived, mainly, at the Palace of Whitehall and was guarded there by Household Cavalry.
In 1689, the court moved to St James's Palace, which was guarded by the Foot Guards.
When Queen Victoria moved into Buckingham Palace in 1837, the Queen's Guard remained at St James's Palace, with a detachment guarding Buckingham Palace, as it still does today.
The Queen’s Guard is commanded by a Captain (who usually holds the rank of Major), and each Detachment is commanded by a Lieutenant.
The Colour of the Battalion providing the Guard is carried by a Second Lieutenant (who is known as the Ensign).
The handover is accompanied by a Guards band. The music played ranges from traditional military marches to songs from films and musicals and even familiar pop songs.
When The Queen is in residence, there are four sentries at the front of the building. When she is away there are two.
