One of these being that Prince William’s future sister in law must sacrifice her wedding bouquet by laying it on the grave of the Unknown Warrior in Westminster Abbey following her big day.
Meghan will have to say goodbye to any of her own plans she had for her bouquet – but why?
The tradition started years ago in 1923 when the late Queen Mother, Lady Elizabeth Bowes-Lyon, laid her wedding bouquet on the grave following her marriage to King George VI.
The Queen’s Mother did this in memory of her brother, Fergus, who died during war in 1915.
The Unknown Warrior grave is the burial place of an unidentified solider killed in the First World War, and represents all the soldiers who lost their lives in war.
When Queen Elizabeth II married Phillip, she laid her bouquet – made from orchids – to keep the tradition going and pay her respects.
When the Duchess of Cambridge, Kate Middleton, and the Duke of Cambridge, Prince William, married at Westminster Abbey in 2001, her bouquet was later taken to the grave.
Meghan and Harry are not wedding at Westminster Abbey, however, the couple could make arrangements for the bouquet to be laid at the Tomb of the Unknown Warrior later.
