After the ceremony, Louis and his sister Charlotte checked out the scene below from a window in Buckingham Palace. You might remember that Prince George did the same thing two years ago! These kids love to look out the window.

Trooping the Colour is held each year to celebrate the queen's "official birthday," which is different than her actual birthday (April 21).
