What is Trooping the Colour?
The special event gives avid royal watchers the chance to see the modern monarchy in their element - big hats, bright colours, royal waves and all!
The event is one of the most spectacular days in the royal calendar and dates all the way back to the 17th century.
Trooping the Colour is performed by regiments of the British and Commonwealth armies. In the past, it took place on battlefields and regiment's colours or flags were used as rallying points.
These days, Trooping the Colour is a celebratory parade in honour of the Queen's birthday - despite it actually being on April 21.

It is carried out by fully trained troops from the Household Division (Foot Guards and Household Cavalry) on Horse Guards Parade in Whitehall.
It is expected that over 1,400 officers, 400 musicians and 200 horses will attend. The Queen herself will travel by carriage from Buckingham Palace to Horse Guards Parade across St. James's Park to inspect her troops, receive a royal salute and take a salute of her own.
The glorious event has been watched by generations of the Royal Family, invited guests and members of the public.
In honour of this exciting day, we take a look back at the royal family enjoying the Trooping the Colour in all its pomp, fanfare and glory.
