Crowds lined the route, as the troops marched past in their finery, hoping to catch a glimpse of members of the Royal Family as they rode past in the famous historic carriages.
For British soldier and Guardsman Charanpreet Singh Lall the day was extra special, for it marked the first time a member of the Coldstream Guards has taken part wearing a turban.
The 22-year-old from Leicester told the Press Association: “I hope that people watching, that they will just acknowledge it and that they will look at it as a new change in history”.
The 92-year-old queen watched the ceremony from a dais and inspected the lines of guardsmen in their iconic bearskin hats – and turbans.
The spectacle included an appearance by Prince Harry and his new wife the Duchess of Sussex (former American actress Meghan Markle). The whole Royal Family, including Prince William and Duchess of Cambridge (Kate Middleton), then joined other members of the royal family on the balcony at Buckingham Palace to watch a Royal Air Force fly by.
