The sun beamed down on the Queen as she left St George's Chapel, in Windsor Castle, to cheers from crowds after attending the annual Order of the Garter Service (pictured left) this afternoon. The monarch’s cloak was held by a young guard as her members of the royal family including Princess Anne and the Duke and Duchess of Sussex exited the venue. Her Majesty arrived at the chapel by state limousine earlier today while the majority of members of the order, including the Prince of Wales and Duke of Cambridge (both right), paraded through the grounds of the castle to the event. Wearing velvet robes and a plumed hat, the Queen, who is sovereign of the order, waved to the hundreds of supporters who gathered outside Windsor Castle to witness the special event (inset). Today's ceremony is part of a 700-year tradition founded by Edward III in 1348, and honours those who have been knighted in recognition of their public service. Knights of the Garter are chosen personally by the Sovereign to honour those who have held public office, who have contributed in a particular way to national life or who have served the Sovereign personally.
