The Royals Are Ready for Christmas—See the Stunning Decorations at Windsor Castle

Meanwhile, other members of the staff can also be seen adding decorations to the state dining room, which has been laid with "silver-gilt pieces from the Grand Service" used by past royals, and are "still used today by the queen and her guests at state banquets," according to the Royal Collection Staff.

This year the queen will celebrate the holidays without the Duke and Duchess of Sussex, who are reportedly spending the holidays with their baby and Markle's mother, Doria Ragland.

The royal couple announced their plans in a statement on November 13.

"The Duke and Duchess of Sussex are looking forward to extended family time toward the end of this month. Having spent the last two Christmases at Sandringham, Their Royal Highnesses will spend the holiday this year, as a new family, with the Duchess’s mother Doria," a spokesperson said. "This decision is in line with precedent set previously by other members of the royal family, and has the support of her Majesty the Queen."
