The annual “Trooping the Colour” ceremony was held to mark Queen Elizabeth’s official birthday. The parade originates from traditional battle preparations. More than 1,000 soldiers, horses and musicians took part in the celebration.

The Queen’s birthday is actually on April 21 but broadcast commentator Dickie Arbiter, a former spokesman for Her Majesty, told CBS News, “The idea of doing it after her birthday was really Edward VII‘s idea at the beginning of the 20th century. He thought, as everybody else does think, that come [the summer] the weather is better. It really isn’t, so you take the chance.”

Here’s a snapshot of the vibrant celebration:
