There are crowds as far as the eye can see here on the Royal Mile in Edinburgh - a sense of comfort in gathering together.
People of all ages have been queuing along the metal barriers outside St Giles’ Cathedral since before 06:00 as they wait to pay their respects to the Queen.
They include thousands of people who have travelled far and wide to witness this moment in history.
Viola Henkenhaf, 18, booked her trains and accommodation as soon as Her Majesty’s death was announced on Thursday. The teenager has travelled from south-west Germany. She didn’t want to miss this opportunity to convey her feelings.
She tells me how important the Queen was to her generation - and the emotional toll her passing has taken on her and her friends.

An update on King Charles III’s journey to Edinburgh - the monarch and Camilla, the Queen Consort, have just touched down at Edinburgh Airport.
The pair will now head to the Palace of Holyroodhouse in the city, where - together with a band of drums - a guard of honour from the Royal Regiment of Scotland will greet them.
After that, it’ll be time for the Ceremony of the Keys - where Charles is ceremonially handed the keys to Edinburgh.
At 73, King Charles was the longest-serving heir to the throne.
In his address to the nation and Commonwealth on Friday following the death of his "darling Mama" Queen Elizabeth II, he spoke of a desire for continuity.
"Our values have remained, and must remain, constant," he said.
But what will that mean for the former Prince of Wales, who has dedicated so much of his time and energy to his beloved charities and to issues such as climate change?
Now King, Charles has pledged to uphold the "relationship and responsibility towards the Church of England - the Church in which my own faith is so deeply rooted".
His duty to "hold in the greatest respect the precious traditions, freedoms and responsibilities of our unique history and our system of parliamentary government" was also mentioned in his speech.
Charles has become head of the Commonwealth, an association of 56 independent countries and some 2.4 billion people. For 14 of these countries, as well as the UK, the King is head of state.
He is set to continue his mother's commitment to this group of nations, meeting Commonwealth leaders at Buckingham Palace shortly after his accession to the throne.
A minute's silence will be held on Sunday to "mourn and reflect on the life and legacy of Queen Elizabeth II", Downing Street says.
A one-minute silence will take place at 20:00 BST on Sunday 18 September - the night before the Queen's funeral.
The prime minister's official spokesman says the silence can be marked "privately at home on your own or with friends and neighbours, out on your doorstep or street with neighbours, or at any locally arranged community events and vigils".
"We encourage local community groups, clubs and other organisations to mark this moment of reflection. And if you are overseas, people are encouraged to mark the silence at their local time."
The spokesman says the silence will be a "shared national moment of reflection".
The Queen's favourite corgi - Susan - was given to her as an 18th birthday present.
She loved her so much she decided to create a Susan dynasty. Here you have an overview of the royal corgis' family tree, though not all of the Queen's dogs were registered.

The smell of fresh flowers fills the air in Green Park.
This corner of central London beside Buckingham Palace has become a centre of mourning, with thousands upon thousands of floral tributes laid around trees and on the grass.
It is quiet, with people trickling between the rows of flowers and messages - some respectfully whispering what she meant to them and others taking a moment alone, looking close to tears.
There are images of the Queen dangling from tree branches and helium balloons swaying in the breeze.
Some of the handwritten notes read: "Our hearts are shattered," "thank you for everything" and "a world without you is unimaginable".

Justin Welby, the Archbishop of Canterbury, was among the 1,200 people in Westminster Hall to witness King Charles III’s first address to both houses of Parliament.
Speaking in Parliament’s central lobby, after the ceremony, he told me that he had been struck by "the sheer continuity that these institutions provide".
"Traditions give us enormous continuity. They hold us at moments like this. There is no uncertainty. Everything moves as it should move and that is a good thing at a time like this."
The plane taking King Charles III and Camilla, the Queen Consort, to Edinburgh has taken off.

A home of history, it hosted Henry VIII’s Coronation Banquet in 1509.
The trial of Guy Fawkes in 1606.
Today, in front of me, row upon row of blue chairs, upon them an audience of around 900 in black.
During the addresses, a sea of thoughtful, contemplative faces.
The King looked occasionally towards the two Speakers, occasionally towards the audience, occasionally the floor.
The Queen Consort looked straight ahead.
Afterwards, the King managed a few smiles as he acknowledged various familiar faces in the congregation.
King Charles III and Camilla, the Queen Consort, have left Westminster Hall.
Charles and Camilla will fly to Edinburgh, where the King will walk behind the Queen's coffin from the Palace of Holyroodhouse to St Giles' Cathedral.
The King will later meet Scotland's First Minister Nicola Sturgeon before he attends Scottish Parliament to receive a motion of condolence.

Image source, ReutersThe King has ended his address and the national anthem is now played in Westminster Hall.
Image source, PA MediaThe King says he is deeply grateful for the addresses of condolences from MPs and peers which "so touchingly encompass" what the Queen "meant to us all".
He makes reference to Shakespeare's Henry VIII, where Elizabeth I is described as "a pattern to all princes living".
He says he cannot help but feel the weight of history which surrounds those in Westminster Hall and "reminds us of vital Parliamentary traditions, to which MPs and peers dedicate themselves".
"Parliament is the living and breathing instrument of our democracy," he says.
He says connections to "my darling late mother" are seen all around, from the Silver Jubilee fountain in New Palace Yard to the sundial in Old Palace Yard marking her Golden Jubilee.
He says the Great Bell of Big Ben - "one of the most powerful symbols of our nation" - will mark the late Queen's progress from Buckingham Palace to Parliament later this week.
King Charles III is now responding to messages of condolences he has received from Lord Speaker and the Speaker of the House of Commons on behalf of MPs and peers.
