Trooping the Colour is an annual event that takes place on Horse Guards Parade near London's St James's Park, marking The Queen's official birthday.
The ceremony of Trooping the Colour is full of military pomp and pageantry as The Queen carries out an inspection of the troops from the Household Division.
The Queen then leads the troops down the Mall to Buckingham Palace, one of London's most famous landmarks.
History of Trooping the Colour
After existing in various forms from around 1700, the Trooping the Colour ceremony was restored in 1820 on the accession of King George IV.
The main aspects of the parade have changed very little since then. Trooping the Colour has been held each year in London, apart from during the world wars and a national rail strike in 1955.
Although the official birthday is celebrated in June, Queen Elizabeth II's actual birthday is in April. Monarchs are traditionally given a second birthday if they were born in winter, in case the weather is unsuitable for an outdoor event!
