Queen Elizabeth was buried with her husband, Prince Philip.
Britain's Queen Elizabeth II "died peacefully" on Thursday, Sept. 8, at Balmoral Castle, the British royal family's estate in Aberdeenshire, Scotland, according to a statement from Buckingham Palace. She was 96.
Elizabeth was Britain's longest-reigning monarch. She ascended to the throne in 1952 and, in June, celebrated her Platinum Jubilee, marking 70 years as queen.
King Charles III and his siblings, Princess Anne and Princes Andrew and Edward, held a vigil at their mother’s coffin at St. Giles’ Cathedral in Scotland.
On Tuesday, Princess Anne will travel with the queen's coffin to London.
King Charles III was greeted by Scotland's First Minister Nicola Sturgeon when he arrived at Scottish Parliament on Monday.
Charles said to Parliament members, "I know that the Scottish Parliament and the people of Scotland share with me a profound sense of grief at the death of my beloved mother. Through all the years of her reign, The Queen, like so many generations of our family before her, found in the hills of this land, and in the hearts of its people, a haven and a home. My mother felt, as I do, the greatest admiration for the Scottish people, for their magnificent achievements and their indomitable spirit."
Charles said he’s passing to his son Prince William the title of "Duke of Rothesay, and the other Scottish titles which I have had the honour to carry for so long."
He continued, "I take up my new duties with thankfulness for all that Scotland has given me, with resolve to seek always the welfare of our country and its people, and with wholehearted trust in your goodwill and good counsel as we take forward that task together."
The queen’s coffin has arrived inside St. Giles' Cathedral in Edinburgh, Scotland.
The wreath of flowers on the coffin includes dried white heather from the queen’s beloved Balmoral Castle in Scotland.
Britain's new Prime Minister Liz Truss was among the attendees at the St. Giles service.
After the service, the coffin will remain at the cathedral for 24 hours so the people of Scotland can pay their respects.
Queen Elizabeth II’s four children -- the new King Charles III, Princess Anne and Princes Andrew and Edward -- are walking behind the hearse carrying her coffin from Palace of Holyroodhouse to St. Giles' Cathedral in Scotland.
The walk is nearly one mile.
The people of Scotland have lined up to silently watch the procession.
The coffin will lie in rest at St. Giles’ Cathedral on Monday. The coffin will be flown to London on Tuesday.
