Royal Family Solemnly Commemorates Remembrance Day 2018 In London

Prince Philip stayed in, but the rest of the family was out and about.

Britain's royal family marked the 100th anniversary of the armistice that ended WWI with a special commemoration on Sunday.

Queen Elizabeth attended a service Sunday morning at The Cenotaph, a war memorial in London. Prince Philip, who retired from many of his public duties in the summer of 2017, did not attend. But her son, Prince Charles and his wife, Camilla, Duchess of Cornwall, were there, as well as the Duke and Duchess of Cambridge and the Duke and Duchess of Sussex. British Prime Minister Theresa May also attended, as did the German President Frank-Walter Steinmeier.

Prince Charles lay a wreath on behalf of his mother. Prince William laid his own wreath, as did Prince Harry.

If you're wondering why the Queen wears so many poppies, by the way, there are a few theories about that: some people say her five flowers represent five branches of the military: the army, the navy, the air force, the civil defence, and women's troops. It's also possible that it's a custom-made brooch, rather than five individual poppies.

On Sunday evening, the royals attended a service to mark the Armistice at Westminster Abbey, where the Queen and the German president both laid flowers at the Grave of the Unknown Warrior in front of a congregation of about 2,000 people.
