The Queen joins Prince Charles and William for annual Garter Day service in front of huge crowds at Windsor Castle

WEEKS after Windsor played host to Meghan and Harry’s wedding, another large crowd has turned out to see the Queen, don her finest garb for an annual royal event.

THE full pomp and ceremony of the royal family was put on show overnight as crowds flocked to celebrate the annual Order of the Garter.

Donning a velvet robe and plumed hat, the Queen was joined by Prince Charles and Prince William for the event — one of the most prestigious services in the royal calendar, reports The Sun.

The 92-year-old monarch arrived decked out in glistening insignia to Windsor Castle for the annual event in a statement limousine, with huge crowds flocking to greet her.

It’s an important event for the Queen who is the Sovereign of the Order of the Garter.

The event celebrates the oldest and most senior order of knighthood in the United Kingdom, making it one of the most prestigious events in the royal calendar.

The second-in-line to the throne was made a member of the order in 2008 — two years before he married Kate Middleton.

The annual event celebrates the senior British order of Chivalry, which dates back to 1348.

It was set up by Edward III, with the Royal Family still marking the ceremony today.

It is said King Edward had been inspired by the tales of King Arthur when he set up the group of honourable knights and called them the Order of the Garter.

The event is held at St George’s Chapel — which recently saw Prince Harry and Meghan Markle tie the knot — with it the order’s spiritual home since the Middle Ages.

And while Knights — who can be both male and female — were previously chosen from aristocracy, members are today chosen in recognition for 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.

Prime Minister Sir Winston Churchill was even one of the personally chosen knights.
