Her Late Majesty is buried alongside her late husband, the Duke of Edinburgh, within the King George VI Memorial Chapel.
HELLO! understands that other members of the royal family have paid their respects privately at the chapel on Friday morning.
Meanwhile, the King and Queen attended a private church service at Crathie Kirk near to the Balmoral estate.

Harry's appearance comes after he paid tribute to his late grandmother during his speech at the WellChild Awards in London on Thursday evening.
At the ceremony, the Duke reflected on the events of 12 months ago when he was forced to miss the awards as he rushed to Balmoral in Aberdeenshire after the Queen was taken ill.

"As you also probably know, she would have been the first person to insist that I still come to be with you all instead of going to her, and that’s precisely why I know exactly one year on that she is looking down on all of us tonight, happy we’re together, continuing to spotlight such an incredible community."
